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

Configuration as Code Plugin logs the changes it applies to the Jenkins system log. Secrets such as passwords should be masked (i.e. replaced with asterisks) in that log to prevent accidental disclosure. Configuration as Code Plugin inspects the type and looks for a field, getter, or constructor argument corresponding to the property, making the secret detection much more robust for the purpose of log message masking. This was implemented in the fix for SECURITY-1279 in the 2019-07-31 security advisory.

That fix was incomplete and did not cover a log message written to the logger io.jenkins.plugins.casc.impl.configurators.DataBoundConfigurator.

Configuration as Code Plugin now uses the same secret detection for these log messages.

As a workaround, administrators can configure the logging level of the logger io.jenkins.plugins.casc.impl.configurators.DataBoundConfigurator to a level that does not include these messages. Configuration as Code Plugin 1.25 and earlier logs these messages at the INFO level, Configuration as Code Plugin 1.26 logs them at FINE. See the logging documentation for details.

Detection & mitigation playbook

Open-source dependency

  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for io.jenkins:configuration-as-code, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

  2. Fix

    Update io.jenkins:configuration-as-code to 1.27 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-7c3v-vc3x-x789 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.
