SummaryThis notification is related to the use of specific values for the region input field when calling AWS services. An actor with access to the environment in which the SDK is used could set the region input field to an invalid value. A defense-in-depth enhancement has been implemented in the AWS SDK for Rust. This enhancement validates that a region used to construct an endpoint URL is a valid host label. The change was released on November 6, 2025. This advisory is informational to help customers understand their responsibilities regarding configuration security. ImpactCustomer applications could be configured to improperly route AWS API calls to non-existent or non-AWS hosts. While the SDK was functioning safely within the requirements of the shared responsibility model, additional safeguards have been added to support secure customer implementations. Impacted versions: All versions prior to November 6, 2025 release PatchesOn November 6, 2025, an enhancement [1] was made to the AWS SDK for Rust release, which validates the formatting of a region, providing additional safeguards. WorkaroundsNo workarounds are needed, but as always developers should ensure that their application is following security best practices:

SummaryThis notification is related to the use of specific values for the region input field when calling AWS services. An actor with access to the environment in which the SDK is used could set the region input field to an invalid value. A defense-in-depth enhancement has been implemented in the AWS SDK for Rust. This enhancement validates that a region used to construct an endpoint URL is a valid host label. The change was released on November 6, 2025. This advisory is informational to help customers understand their responsibilities regarding configuration security. ImpactCustomer applications could be configured to improperly route AWS API calls to non-existent or non-AWS hosts. While the SDK was functioning safely within the requirements of the shared responsibility model, additional safeguards have been added to support secure customer implementations. Impacted versions: All versions prior to November 6, 2025 release PatchesOn November 6, 2025, an enhancement [1] was made to the AWS SDK for Rust release, which validates the formatting of a region, providing additional safeguards.
