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 Metrics Plugin 4.0.2.8 and earlier stores an access key unencrypted in its global configuration file jenkins.metrics.api.MetricsAccessKey.xml on the Jenkins controller as part of its configuration.

This access key can be viewed by users with access to the Jenkins controller file system.

Jenkins Metrics Plugin 4.0.2.8.1 stores access key encrypted once its configuration is saved again.

Additionally, the token value is only displayed once when it is generated.

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:metrics, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

  2. Fix

    Update org.jenkins-ci.plugins:metrics to 4.0.2.8.1 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-gg9m-x3cg-69vh 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.
