Description

A sandbox bypass vulnerability involving various casts performed implicitly by the Groovy language runtime in Jenkins Pipeline: Groovy Plugin 2802.v5ea_628154b_c2 and earlier allows attackers with permission to define and run sandboxed scripts, including Pipelines, to bypass the sandbox protection and execute arbitrary code in the context of the Jenkins controller JVM. Pipeline: Groovy Plugin 2803.v1a_f77ffcc773 intercepts Groovy casts performed implicitly by the Groovy language runtime

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 2803.v1a_f77ffcc773 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-mqc2-w9r8-mmxm 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.
