CVE-2026-57287 · Severity: medium · CVSS 4.3 · Published 2026-06-24

The Jenkins Job Configuration History Plugin, which tracks changes to job and agent settings, fails to hide sensitive encrypted data in its history logs. This allows users with limited read-only access to view encrypted secrets, such as authentication tokens, which they should not be able to see. While the data is encrypted, exposing these values increases the risk of credential theft or unauthorized access if the encryption can be bypassed.

Technologies: [org.jenkins-ci.plugins:jobConfigHistory (Maven)](https://junglewise.ai/threats/technologies/org-jenkins-ci-plugins-jobconfighistory). Vendors: [Jenkins Project](https://junglewise.ai/threats/vendors/jenkins-project), [Maven](https://junglewise.ai/threats/vendors/maven).

**Am I affected by CVE-2026-57287?** Check whether you run Jenkins Project Job Configuration History Plugin or org.jenkins-ci.plugins:jobConfigHistory (Maven) at an affected version. Junglewise does that check for you around the clock: connect your code, cloud and domains, and it matches new vulnerabilities like this one against what you actually run and tells you when one reaches you.

## How to fix

- org.jenkins-ci.plugins:jobConfigHistory (Maven): upgrade to 1367 or later

  ```


## Technical details

The Job Configuration History Plugin (up to version 1356.ve360da_6c523a_) fails to redact encrypted secret values when displaying historical job and agent configurations. This occurs specifically within the 'View as XML' (RAW) feature and the configuration diff views. An attacker with 'Item/Extended Read' permissions—who normally should not have access to sensitive configuration details—can view these encrypted strings (e.g., build trigger tokens). While the values remain encrypted, Jenkins security policy typically requires these to be redacted for users without 'Item/Configure' permissions to prevent offline attacks or accidental exposure. The vulnerability is tracked as SECURITY-3742.
