Description

Jenkins Pipeline: Groovy Plugin 3990.vd281dd77a_388 and earlier, except 3975.3977.v478dd9e956c3 does not check whether the main (Jenkinsfile) script for a rebuilt build is approved, allowing attackers with Item/Build permission to rebuild a previous build whose (Jenkinsfile) script is no longer approved. This allows attackers with Item/Build permission to rebuild a previous build whose (Jenkinsfile) script is no longer approved. Pipeline: Groovy Plugin 3993.v3e20a_37282f8 refuses to rebuild a build whose main (Jenkinsfile) script is unapproved.

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

  2. Fix

    Update org.jenkins-ci.plugins.workflow:workflow-cps to 3993.v3e20a or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-mrpr-vr82-x88r 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.

Fixing This On Your OS

If you run this on a Linux distribution, patch through your package manager against the distro's own security advisory below — it tracks the exact backported fix for your release, which can ship on a different timeline (and sometimes a different severity) than the upstream project.

Red HatImportant

This vulnerability is considered of important severity rather than moderate because it allows attackers with the `Item/Build` permission to trigger the execution of previously unapproved Jenkinsfiles during the rebuild process. Jenkinsfiles often contain critical pipeline scripts that can interact with sensitive…
