Real-World Exposure

1 pkg affected
☕org.jenkins-ci.plugins:periodicbackup

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

The Periodic Backup Plugin did not perform any permission checks, allowing any user with Overall/Read access to change its settings, trigger backups, restore backups, download backups, and also delete all previous backups via log rotation. Additionally, the plugin was not requiring requests to its API be sent via POST, thereby opening itself to Cross-Site Request Forgery attacks.

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

  2. Fix

    Update org.jenkins-ci.plugins:periodicbackup to 1.5 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-5293-3fgp-cr3x 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.
