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

Copy Artifact Plugin 1.43.1 and earlier performs improper permission checks when determining whether a build can copy artifacts from another project build. This allows attackers, usually with Job/Configure permission, to configure jobs to copy artifacts from jobs they have no permission to access.

Copy Artifact Plugin 1.44 now properly performs permission checks when copying artifacts. When updating the plugin from a previous version, the previous behavior is retained ("Migration mode"). To enable the additional protections, switch to the new "Production mode". Doing so may cause existing jobs to fail to copy artifacts. For more information see the plugin documentation.

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

  2. Fix

    Update org.jenkins-ci.plugins:copyartifact to 1.44 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2020-2183 is resolved across your whole dependency graph.

  3. Workarounds

    Close the privilege gap rather than the entry point: audit which accounts, roles and service identities can reach the affected operation, drop the component to the least privilege it actually needs, and review file and directory permissions created by earlier installs — a default left in place is what makes this reachable.
