Real-time download stats are indexed for npm and PyPI packages. This vulnerability affects Maven packages — download data is not available via public APIs for these ecosystems.

Description

Jenkins 2.503 and earlier, LTS 2.492.2 and earlier does not perform a permission check in an HTTP endpoint.

This allows attackers with Computer/Create permission but without Computer/Configure permission to copy an agent, gaining access to encrypted secrets in its configuration.

This is due to an incomplete fix of SECURITY-3495/CVE-2025-27622.

Jenkins 2.504, LTS 2.492.3 requires Computer/Configure permission to copy an agent containing secrets.

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.main:jenkins-core, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

  2. Fix

    Update org.jenkins-ci.main:jenkins-core to 2.504 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-wr6w-jxg7-qpfh is resolved across your whole dependency graph.

  3. Workarounds

    Put an independent control in front of the weakness: restrict the affected endpoint or interface to trusted networks, require an additional authentication factor or proxy-level check, and invalidate existing sessions and credentials in case the flaw has already been used.
