Snowflake Connector for Python improperly verifies TLS hostnames
Critical
Network
Low
None
None
Improper TLS hostname verification in Snowflake Connector for Python versions prior to 4.7.1 and 3.18.1 may have allowed a network-positioned attacker to bypass certificate hostname validation on HTTPS connections made by the connector. An attacker with on-path network access could exploit this by intercepting or redirecting network traffic and presenting a certificate signed by any trusted CA for any domain, causing the connector to accept connections without validating that the certificate matched the requested hostname. Successful exploitation requires an on-path traffic interception capability (e.g. ARP/DNS poisoning, rogue access point, BGP hijacking, or malicious proxy/exit node). This vulnerability may have exposed credentials, query data, and staged file contents to interception and tampering, and may have enabled the attacker to issue arbitrary SQL within the context of the victim's connector session. Impact is limited by the privileges of the affected Snowflake role. The fix is available in Snowflake Connector for Python versions 4.7.1 and 3.18.1. Users must manually upgrade. Affected versions

Snowflake Connector for Python improperly verifies TLS hostnames
Critical
Network
Low
None
None
Improper TLS hostname verification in Snowflake Connector for Python versions prior to 4.7.1 and 3.18.1 may have allowed a network-positioned attacker to bypass certificate hostname validation on HTTPS connections made by the connector. An attacker with on-path network access could exploit this by intercepting or redirecting network traffic and presenting a certificate signed by any trusted CA for any domain, causing the connector to accept connections without validating that the certificate matched the requested hostname. Successful exploitation requires an on-path traffic interception capability (e.g. ARP/DNS poisoning, rogue access point, BGP hijacking, or malicious proxy/exit node). This vulnerability may have exposed credentials, query data, and staged file contents to interception and tampering, and may have enabled the attacker to issue arbitrary SQL within the context of the victim's connector session. Impact is limited by the privileges of the affected Snowflake role. The fix is available in Snowflake Connector for Python versions 4.7.1 and 3.18.1. Users must manually upgrade. Affected versions

Snowflake Connector for Python improperly verifies TLS hostnames
Critical
Network
Low
None
None
Improper TLS hostname verification in Snowflake Connector for Python versions prior to 4.7.1 and 3.18.1 may have allowed a network-positioned attacker to bypass certificate hostname validation on HTTPS connections made by the connector. An attacker with on-path network access could exploit this by intercepting or redirecting network traffic and presenting a certificate signed by any trusted CA for any domain, causing the connector to accept connections without validating that the certificate matched the requested hostname. Successful exploitation requires an on-path traffic interception capability (e.g. ARP/DNS poisoning, rogue access point, BGP hijacking, or malicious proxy/exit node). This vulnerability may have exposed credentials, query data, and staged file contents to interception and tampering, and may have enabled the attacker to issue arbitrary SQL within the context of the victim's connector session. Impact is limited by the privileges of the affected Snowflake role. The fix is available in Snowflake Connector for Python versions 4.7.1 and 3.18.1. Users must manually upgrade. Affected versions

Snowflake Connector for Python improperly verifies TLS hostnames
Critical
Network
Low
None
None
Improper TLS hostname verification in Snowflake Connector for Python versions prior to 4.7.1 and 3.18.1 may have allowed a network-positioned attacker to bypass certificate hostname validation on HTTPS connections made by the connector. An attacker with on-path network access could exploit this by intercepting or redirecting network traffic and presenting a certificate signed by any trusted CA for any domain, causing the connector to accept connections without validating that the certificate matched the requested hostname. Successful exploitation requires an on-path traffic interception capability (e.g. ARP/DNS poisoning, rogue access point, BGP hijacking, or malicious proxy/exit node). This vulnerability may have exposed credentials, query data, and staged file contents to interception and tampering, and may have enabled the attacker to issue arbitrary SQL within the context of the victim's connector session. Impact is limited by the privileges of the affected Snowflake role. The fix is available in Snowflake Connector for Python versions 4.7.1 and 3.18.1. Users must manually upgrade. Affected versions

Snowflake Connector for Python improperly verifies TLS hostnames
Critical
Network
Low
None
None
Improper TLS hostname verification in Snowflake Connector for Python versions prior to 4.7.1 and 3.18.1 may have allowed a network-positioned attacker to bypass certificate hostname validation on HTTPS connections made by the connector. An attacker with on-path network access could exploit this by intercepting or redirecting network traffic and presenting a certificate signed by any trusted CA for any domain, causing the connector to accept connections without validating that the certificate matched the requested hostname. Successful exploitation requires an on-path traffic interception capability (e.g. ARP/DNS poisoning, rogue access point, BGP hijacking, or malicious proxy/exit node). This vulnerability may have exposed credentials, query data, and staged file contents to interception and tampering, and may have enabled the attacker to issue arbitrary SQL within the context of the victim's connector session. Impact is limited by the privileges of the affected Snowflake role. The fix is available in Snowflake Connector for Python versions 4.7.1 and 3.18.1. Users must manually upgrade. Affected versions

Snowflake Connector for Python improperly verifies TLS hostnames
Critical
Network
Low
None
None
Improper TLS hostname verification in Snowflake Connector for Python versions prior to 4.7.1 and 3.18.1 may have allowed a network-positioned attacker to bypass certificate hostname validation on HTTPS connections made by the connector. An attacker with on-path network access could exploit this by intercepting or redirecting network traffic and presenting a certificate signed by any trusted CA for any domain, causing the connector to accept connections without validating that the certificate matched the requested hostname. Successful exploitation requires an on-path traffic interception capability (e.g. ARP/DNS poisoning, rogue access point, BGP hijacking, or malicious proxy/exit node). This vulnerability may have exposed credentials, query data, and staged file contents to interception and tampering, and may have enabled the attacker to issue arbitrary SQL within the context of the victim's connector session. Impact is limited by the privileges of the affected Snowflake role. The fix is available in Snowflake Connector for Python versions 4.7.1 and 3.18.1. Users must manually upgrade. Affected versions

Snowflake Connector for Python improperly verifies TLS hostnames
Critical
Network
Low
None
None
Improper TLS hostname verification in Snowflake Connector for Python versions prior to 4.7.1 and 3.18.1 may have allowed a network-positioned attacker to bypass certificate hostname validation on HTTPS connections made by the connector. An attacker with on-path network access could exploit this by intercepting or redirecting network traffic and presenting a certificate signed by any trusted CA for any domain, causing the connector to accept connections without validating that the certificate matched the requested hostname. Successful exploitation requires an on-path traffic interception capability (e.g. ARP/DNS poisoning, rogue access point, BGP hijacking, or malicious proxy/exit node). This vulnerability may have exposed credentials, query data, and staged file contents to interception and tampering, and may have enabled the attacker to issue arbitrary SQL within the context of the victim's connector session. Impact is limited by the privileges of the affected Snowflake role. The fix is available in Snowflake Connector for Python versions 4.7.1 and 3.18.1. Users must manually upgrade. Affected versions

IssueSnowflake recently learned about and remediated a set of vulnerabilities in the Snowflake Connector for Python. Under specific conditions, certain users credentials (or portions of those credentials) were logged locally by the Connector to the users own systems. The credentials were not logged by Snowflake. These vulnerabilities affect versions up to and including 3.12.2. Snowflake fixed the issue in version 3.12.3. Vulnerability DetailsWhen the logging level was set by the user to DEBUG, the Connector could have logged Duo passcodes (when specified via the “passcode” parameter) and Azure SAS tokens. Additionally, the SecretDetector logging formatter, if enabled, contained bugs which caused it to not fully redact JWT tokens and certain private key formats. SolutionSnowflake released version 3.12.3 of the Snowflake Connector for Python, which fixes these issues. We recommend users upgrade to version 3.12.3 and review their logs for any potentially sensitive information that may have been captured.

Snowflake Connector for Python improperly verifies TLS hostnames
Critical
Network
Low
None
None
Improper TLS hostname verification in Snowflake Connector for Python versions prior to 4.7.1 and 3.18.1 may have allowed a network-positioned attacker to bypass certificate hostname validation on HTTPS connections made by the connector. An attacker with on-path network access could exploit this by intercepting or redirecting network traffic and presenting a certificate signed by any trusted CA for any domain, causing the connector to accept connections without validating that the certificate matched the requested hostname. Successful exploitation requires an on-path traffic interception capability (e.g. ARP/DNS poisoning, rogue access point, BGP hijacking, or malicious proxy/exit node). This vulnerability may have exposed credentials, query data, and staged file contents to interception and tampering, and may have enabled the attacker to issue arbitrary SQL within the context of the victim's connector session. Impact is limited by the privileges of the affected Snowflake role. The fix is available in Snowflake Connector for Python versions 4.7.1 and 3.18.1. Users must manually upgrade. Affected versions

Snowflake Connector for Python improperly verifies TLS hostnames
Critical
Network
Low
None
None
Improper TLS hostname verification in Snowflake Connector for Python versions prior to 4.7.1 and 3.18.1 may have allowed a network-positioned attacker to bypass certificate hostname validation on HTTPS connections made by the connector. An attacker with on-path network access could exploit this by intercepting or redirecting network traffic and presenting a certificate signed by any trusted CA for any domain, causing the connector to accept connections without validating that the certificate matched the requested hostname. Successful exploitation requires an on-path traffic interception capability (e.g. ARP/DNS poisoning, rogue access point, BGP hijacking, or malicious proxy/exit node). This vulnerability may have exposed credentials, query data, and staged file contents to interception and tampering, and may have enabled the attacker to issue arbitrary SQL within the context of the victim's connector session. Impact is limited by the privileges of the affected Snowflake role. The fix is available in Snowflake Connector for Python versions 4.7.1 and 3.18.1. Users must manually upgrade. Affected versions

IssueSnowflake recently learned about and remediated a set of vulnerabilities in the Snowflake Connector for Python. Under specific conditions, certain users credentials (or portions of those credentials) were logged locally by the Connector to the users own systems. The credentials were not logged by Snowflake. These vulnerabilities affect versions up to and including 3.12.2. Snowflake fixed the issue in version 3.12.3. Vulnerability DetailsWhen the logging level was set by the user to DEBUG, the Connector could have logged Duo passcodes (when specified via the “passcode” parameter) and Azure SAS tokens. Additionally, the SecretDetector logging formatter, if enabled, contained bugs which caused it to not fully redact JWT tokens and certain private key formats. SolutionSnowflake released version 3.12.3 of the Snowflake Connector for Python, which fixes these issues. We recommend users upgrade to version 3.12.3 and review their logs for any potentially sensitive information that may have been captured.

IssueSnowflake recently learned about and remediated a set of vulnerabilities in the Snowflake Connector for Python. Under specific conditions, certain users credentials (or portions of those credentials) were logged locally by the Connector to the users own systems. The credentials were not logged by Snowflake. These vulnerabilities affect versions up to and including 3.12.2. Snowflake fixed the issue in version 3.12.3. Vulnerability DetailsWhen the logging level was set by the user to DEBUG, the Connector could have logged Duo passcodes (when specified via the “passcode” parameter) and Azure SAS tokens. Additionally, the SecretDetector logging formatter, if enabled, contained bugs which caused it to not fully redact JWT tokens and certain private key formats. SolutionSnowflake released version 3.12.3 of the Snowflake Connector for Python, which fixes these issues. We recommend users upgrade to version 3.12.3 and review their logs for any potentially sensitive information that may have been captured.

Snowflake Connector for Python improperly verifies TLS hostnames
Critical
Network
Low
None
None
Improper TLS hostname verification in Snowflake Connector for Python versions prior to 4.7.1 and 3.18.1 may have allowed a network-positioned attacker to bypass certificate hostname validation on HTTPS connections made by the connector. An attacker with on-path network access could exploit this by intercepting or redirecting network traffic and presenting a certificate signed by any trusted CA for any domain, causing the connector to accept connections without validating that the certificate matched the requested hostname. Successful exploitation requires an on-path traffic interception capability (e.g. ARP/DNS poisoning, rogue access point, BGP hijacking, or malicious proxy/exit node). This vulnerability may have exposed credentials, query data, and staged file contents to interception and tampering, and may have enabled the attacker to issue arbitrary SQL within the context of the victim's connector session. Impact is limited by the privileges of the affected Snowflake role. The fix is available in Snowflake Connector for Python versions 4.7.1 and 3.18.1. Users must manually upgrade. Affected versions

Under specific conditions, certain users credentials (or portions of those credentials) were logged locally by the Connector to the users own systems. The credentials were not logged by Snowflake. These vulnerabilities affect versions up to and including 3.12.2. Snowflake fixed the issue in version 3.12.3. Vulnerability DetailsWhen the logging level was set by the user to DEBUG, the Connector could have logged Duo passcodes (when specified via the “passcode” parameter) and Azure SAS tokens. Additionally, the SecretDetector logging formatter, if enabled, contained bugs which caused it to not fully redact JWT tokens and certain private key formats. SolutionSnowflake released version 3.12.3 of the Snowflake Connector for Python, which fixes these issues. We recommend users upgrade to version 3.12.3 and review their logs for any potentially sensitive information that may have been captured.

Improper TLS hostname verification in Snowflake Connector for Python versions prior to 4.7.1 and 3.18.1 may have allowed a network-positioned attacker to bypass certificate hostname validation on HTTPS connections made by the connector. An attacker with on-path network access could exploit this by intercepting or redirecting network traffic and presenting a certificate signed by any trusted CA for any domain, causing the connector to accept connections without validating that the certificate matched the requested hostname. Successful exploitation requires an on-path traffic interception capability (e.g. ARP/DNS poisoning, rogue access point, BGP hijacking, or malicious proxy/exit node). This vulnerability may have exposed credentials, query data, and staged file contents to interception and tampering, and may have enabled the attacker to issue arbitrary SQL within the context of the victim's connector session. Impact is limited by the privileges of the affected Snowflake role. The fix is available in Snowflake Connector for Python versions 4.7.1 and 3.18.1. Users must manually upgrade. Affected versions

IssueSnowflake recently learned about and remediated a set of vulnerabilities in the Snowflake Connector for Python. Under specific conditions, certain users credentials (or portions of those credentials) were logged locally by the Connector to the users own systems. The credentials were not logged by Snowflake. These vulnerabilities affect versions up to and including 3.12.2. Snowflake fixed the issue in version 3.12.3. Vulnerability DetailsWhen the logging level was set by the user to DEBUG, the Connector could have logged Duo passcodes (when specified via the “passcode” parameter) and Azure SAS tokens. Additionally, the SecretDetector logging formatter, if enabled, contained bugs which caused it to not fully redact JWT tokens and certain private key formats. SolutionSnowflake released version 3.12.3 of the Snowflake Connector for Python, which fixes these issues. We recommend users upgrade to version 3.12.3 and review their logs for any potentially sensitive information that may have been captured.

Snowflake Connector for Python improperly verifies TLS hostnames
Critical
Network
Low
None
None
Improper TLS hostname verification in Snowflake Connector for Python versions prior to 4.7.1 and 3.18.1 may have allowed a network-positioned attacker to bypass certificate hostname validation on HTTPS connections made by the connector. An attacker with on-path network access could exploit this by intercepting or redirecting network traffic and presenting a certificate signed by any trusted CA for any domain, causing the connector to accept connections without validating that the certificate matched the requested hostname. Successful exploitation requires an on-path traffic interception capability (e.g. ARP/DNS poisoning, rogue access point, BGP hijacking, or malicious proxy/exit node). This vulnerability may have exposed credentials, query data, and staged file contents to interception and tampering, and may have enabled the attacker to issue arbitrary SQL within the context of the victim's connector session. Impact is limited by the privileges of the affected Snowflake role. The fix is available in Snowflake Connector for Python versions 4.7.1 and 3.18.1. Users must manually upgrade. Affected versions

IssueSnowflake recently learned about and remediated a set of vulnerabilities in the Snowflake Connector for Python. Under specific conditions, certain users credentials (or portions of those credentials) were logged locally by the Connector to the users own systems. The credentials were not logged by Snowflake. These vulnerabilities affect versions up to and including 3.12.2. Snowflake fixed the issue in version 3.12.3. Vulnerability DetailsWhen the logging level was set by the user to DEBUG, the Connector could have logged Duo passcodes (when specified via the “passcode” parameter) and Azure SAS tokens. Additionally, the SecretDetector logging formatter, if enabled, contained bugs which caused it to not fully redact JWT tokens and certain private key formats. SolutionSnowflake released version 3.12.3 of the Snowflake Connector for Python, which fixes these issues. We recommend users upgrade to version 3.12.3 and review their logs for any potentially sensitive information that may have been captured.

IssueSnowflake recently learned about and remediated a set of vulnerabilities in the Snowflake Connector for Python. Under specific conditions, certain users credentials (or portions of those credentials) were logged locally by the Connector to the users own systems. The credentials were not logged by Snowflake. These vulnerabilities affect versions up to and including 3.12.2. Snowflake fixed the issue in version 3.12.3. Vulnerability DetailsWhen the logging level was set by the user to DEBUG, the Connector could have logged Duo passcodes (when specified via the “passcode” parameter) and Azure SAS tokens. Additionally, the SecretDetector logging formatter, if enabled, contained bugs which caused it to not fully redact JWT tokens and certain private key formats. SolutionSnowflake released version 3.12.3 of the Snowflake Connector for Python, which fixes these issues. We recommend users upgrade to version 3.12.3 and review their logs for any potentially sensitive information that may have been captured.

Snowflake Connector for Python improperly verifies TLS hostnames
Critical
Network
Low
None
None
Improper TLS hostname verification in Snowflake Connector for Python versions prior to 4.7.1 and 3.18.1 may have allowed a network-positioned attacker to bypass certificate hostname validation on HTTPS connections made by the connector. An attacker with on-path network access could exploit this by intercepting or redirecting network traffic and presenting a certificate signed by any trusted CA for any domain, causing the connector to accept connections without validating that the certificate matched the requested hostname. Successful exploitation requires an on-path traffic interception capability (e.g. ARP/DNS poisoning, rogue access point, BGP hijacking, or malicious proxy/exit node). This vulnerability may have exposed credentials, query data, and staged file contents to interception and tampering, and may have enabled the attacker to issue arbitrary SQL within the context of the victim's connector session. Impact is limited by the privileges of the affected Snowflake role. The fix is available in Snowflake Connector for Python versions 4.7.1 and 3.18.1. Users must manually upgrade. Affected versions

IssueSnowflake recently learned about and remediated a set of vulnerabilities in the Snowflake Connector for Python. Under specific conditions, certain users credentials (or portions of those credentials) were logged locally by the Connector to the users own systems. The credentials were not logged by Snowflake. These vulnerabilities affect versions up to and including 3.12.2. Snowflake fixed the issue in version 3.12.3. Vulnerability DetailsWhen the logging level was set by the user to DEBUG, the Connector could have logged Duo passcodes (when specified via the “passcode” parameter) and Azure SAS tokens. Additionally, the SecretDetector logging formatter, if enabled, contained bugs which caused it to not fully redact JWT tokens and certain private key formats. SolutionSnowflake released version 3.12.3 of the Snowflake Connector for Python, which fixes these issues. We recommend users upgrade to version 3.12.3 and review their logs for any potentially sensitive information that may have been captured.

Snowflake Connector for Python improperly verifies TLS hostnames
Critical
Network
Low
None
None
Improper TLS hostname verification in Snowflake Connector for Python versions prior to 4.7.1 and 3.18.1 may have allowed a network-positioned attacker to bypass certificate hostname validation on HTTPS connections made by the connector. An attacker with on-path network access could exploit this by intercepting or redirecting network traffic and presenting a certificate signed by any trusted CA for any domain, causing the connector to accept connections without validating that the certificate matched the requested hostname. Successful exploitation requires an on-path traffic interception capability (e.g. ARP/DNS poisoning, rogue access point, BGP hijacking, or malicious proxy/exit node). This vulnerability may have exposed credentials, query data, and staged file contents to interception and tampering, and may have enabled the attacker to issue arbitrary SQL within the context of the victim's connector session. Impact is limited by the privileges of the affected Snowflake role. The fix is available in Snowflake Connector for Python versions 4.7.1 and 3.18.1. Users must manually upgrade. Affected versions
