CVE-2023-39152Network attack vector

Credential disclosure via controller API misuse

Published Jul 26, 2023 · Updated Oct 23, 2024

Credentials exposure in Jenkins Gradle Plugin 2.8 allows remote authenticated users to read secrets in build logs via crafted builds. The plugin invokes controller-only APIs from an agent while creating build-log annotations, triggering an exception that bypasses credential masking. Access requires permission to run or influence a Jenkins build, and the bounded impact is disclosure of credentials printed in the affected log.
