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 2.73.1 and earlier, 2.83 and earlier users with permission to create or configure agents in Jenkins could configure a launch method called 'Launch agent via execution of command on master'. This allowed them to run arbitrary shell commands on the master node whenever the agent was supposed to be launched. Configuration of this launch method now requires the Run Scripts permission typically only granted to administrators.

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 2.73.2 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-j472-mcq2-95p6 is resolved across your whole dependency graph.

  3. Workarounds

    Stop passing untrusted input into the interpreter or shell: call the affected binary with an argument array rather than a composed command string, reject anything outside a strict allowlist of expected values, and run the component under an account that cannot reach beyond the work it legitimately does.
