Security readout for executives and security teams
Plain-English summary
This issue exposes passwords stored by the Jenkins Mail Commander Plugin. If an organization uses version 1.0.0 or earlier, people with Jenkins Extended Read permission or access to the controller file system may be able to view passwords saved in job configuration files.
Executive priority
Treat this as a credential exposure issue, not a remote code execution emergency. Prioritize review where Jenkins stores production, deployment, email, or service credentials, especially if many users have read-level administrative access.
Technical view
Jenkins Mail Commander Plugin 1.0.0 and earlier stores passwords unencrypted in Jenkins job config.xml files on the controller. The documented exposure path is read access through Extended Read permission or direct controller file system access. No CVSS score or CWE is provided in the supplied sources.
Likely exposure
Exposure is limited to Jenkins environments using the Mail Commander Plugin 1.0.0 or earlier. Risk is higher on shared Jenkins controllers, broadly delegated Jenkins administration, or systems where file system access is not tightly controlled.
Exploitation context
The supplied sources do not state active exploitation, and CISA KEV status is false. Abuse appears to require authenticated Extended Read permission or controller file system access, but exposed passwords could enable follow-on access depending on what the credentials protect.
Researcher notes
The key evidence is narrow: cleartext password storage in job config.xml and exposure to Extended Read or controller file system access. The supplied bundle does not provide CVSS, CWE, exploit evidence, or a confirmed fixed version.
Mitigation direction
- Identify Jenkins controllers using Mail Commander Plugin 1.0.0 or earlier.
- Check Jenkins and plugin vendor guidance for available updates or remediation notes.
- Restrict Extended Read permission to users with a clear operational need.
- Limit operating system access to Jenkins controller configuration files.
- Rotate passwords that may have been stored in affected job configurations.
Validation and detection
- Inventory installed Jenkins plugins and confirm Mail Commander Plugin version presence.
- Review affected job configurations for stored Mail Commander passwords.
- Audit which users or groups have Jenkins Extended Read permission.
- Review controller file system access for users and service accounts.
- Confirm rotated credentials no longer appear in affected job configurations.
