SummaryWhen verifying SSL certificates, jruby-openssl is not verifying that the hostname presented in the certificate matches the one we are trying to connect to, meaning a MITM could just present any valid cert for a completely different domain they own, and JRuby wouldn't complain. Detailsn/a PoCAn example domain bad.substitutealert.com was created to present the a certificate for the domain s8a.me. The following script run in IRB in CRuby 3.4.3 will fail with ImpactAnybody using JRuby to make requests of external APIs, or scraping the web, that depends on https to connect securely Affected versions
