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

GitHub Pull Request Builder Plugin stored the webhook secret shared between Jenkins and GitHub in plain text. This allowed users with Jenkins controller local file system access and Jenkins administrators to retrieve the stored password. The latter could result in exposure of the passwords through browser extensions, cross-site scripting vulnerabilities, and similar situations. GitHub Pull Request Builder Plugin 1.32.1 and newer stores the webhook secret encrypted on disk.

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

  2. Fix

    Update org.jenkins-ci.plugins:ghprb to 1.32.1 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-876j-4q73-7f56 is resolved across your whole dependency graph.

  3. Workarounds

    Escape or sanitise the affected output on the server side rather than relying on client-side filtering, and add a Content-Security-Policy that blocks inline script execution so injected markup cannot run even if it reaches the page.
