CVE-2025-25291
CRITICAL9.8EPSS 20.8%omniauth-saml has dependency on ruby-saml version with Signature Wrapping Attack issue
發布日:2025/3/12修改日:2026/4/28
描述
ruby-saml provides security assertion markup language (SAML) single sign-on (SSO) for Ruby. An authentication bypass vulnerability was found in ruby-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 entirely different document structures from the same XML input. That allows an attacker to be able to execute a Signature Wrapping attack. This issue may lead to authentication bypass. Versions 1.12.4 and 1.18.0 fix the issue.
