CVE-2025-25292 is fixed in ruby-saml on 1 platform, first by ruby-saml 1.7.2-1ubuntu0.1~esm2, released March 12, 2025. It is not reported as exploited. Patch Radar priority: Routine.
ruby-saml provides security assertion markup language (SAML) single sign-on(SSO) for Ruby. An authentication bypass vulnerability was found inruby-saml prior to versions 1.12.4 and 1.18.0 due to a parser differential.ReXML and Nokogiri parse XML differently, the parsers can generate entirelydifferent document structures from the same XML input. That allows anattacker to be able to execute a Signature Wrapping attack. This issue maylead to authentication bypass. Versions 1.12.4 and 1.18.0 contain a patchfor the issue.
