CVE-2025-25291 – Apache Ruby-SAML XML Parser Signature Wrapping Authentication Bypass

CVE ID : CVE-2025-25291

Published : March 12, 2025, 9:15 p.m. | 1 hour, 40 minutes ago

Description : 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.

Severity: 0.0 | NA
