1 pkg affected

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

Chef Identity Plugin stores the user.pem key in its global configuration file io.chef.jenkins.ChefIdentityBuildWrapper.xml on the Jenkins controller as part of its configuration.

While this key is stored encrypted on disk, in Chef Identity Plugin 2.0.3 and earlier the global configuration form does not mask the user.pem key form field, increasing the potential for attackers to observe and capture it.

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

  2. Remediation status

    The records we use list no patched version of org.jenkins-ci.plugins:chef-identity for CVE-2023-39155. Check the maintainer's advisory, and where your build allows, override or pin the dependency away from the vulnerable range.

  3. Mitigate without a patch

    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.
