CVE-2025-66567 unimportant priority: Debian including 1 source packages (ruby-saml), 2 status rows across 2 suites (bookworm, bullseye): resolved 2.
The ruby-saml library is for implementing the client side of a SAML authorization. ruby-saml versions up to and including 1.12.4 contain an authentication bypass vulnerability due to an incomplete fix for CVE-2025-25292. ReXML and Nokogiri parse XML differently, generating entirely different document structures from the same input. This allows an attacker to execute a Signature Wrapping attack. This issue is fixed in version 1.18.0.
