Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

Keycloak's keycloak-saml-core package, versions before 22.0.13, from 23.0.0 before 24.0.8, and from 25.0.0 before 25.0.6, is affected. The SAML signature validation in the XMLSignatureUtil class decides whether a signature covers the full document or only assertions based on where the signature sits in the XML, not on the Reference element. An attacker who can send crafted SAML responses may bypass validation, which could lead to privilege escalation or impersonation. Upgrade to 22.0.13, 24.0.8, 25.0.6, or a later fixed release.
