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

warnings Plugin 5.0.1 and earlier does not require POST requests for a form validation method intended for testing custom warnings parsers, resulting in a cross-site request forgery (CSRF) vulnerability.

This vulnerability allows attackers to execute arbitrary code.

warnings Plugin 5.0.2 requires POST requests for the affected form validation method.

This vulnerability was caused by an incomplete fix to SECURITY-1295.

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.jvnet.hudson.plugins:warnings, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

  2. Fix

    Update org.jvnet.hudson.plugins:warnings to 5.0.2 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2020-2280 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.
