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

Jenkins Contrast Continuous Application Security Plugin 3.11 and earlier does not perform permission checks in several HTTP endpoints that fill list box options with the names of the configured Contrast metadata.

This allows attackers with Overall/Read permission to enumerate the names of configured Contrast metadata.

Contrast Continuous Application Security Plugin 3.12 requires the appropriate permission to enumerate the configured Contrast metadata.

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:contrast-continuous-application-security, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

  2. Fix

    Update org.jenkins-ci.plugins:contrast-continuous-application-security to 3.12 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2026-57299 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.
