Description

Jenkins SAML Plugin 4.583.vc68232f7018a_ and earlier does not implement a replay cache.

This allows attackers able to obtain information about the SAML authentication flow between a user’s web browser and Jenkins to replay those requests, authenticating to Jenkins as that user.

SAML Plugin 4.583.585.v22ccc1139f55 implements a replay cache that rejects replayed requests.

Detection & mitigation playbook

Open-source dependency

  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for org.jenkins-ci.plugins:saml, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

  2. Fix

    Update org.jenkins-ci.plugins:saml to 4.583.585.v22ccc1139f55 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2025-64131 is resolved across your whole dependency graph.

  3. Workarounds

    If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
