Jenkins · Jenkins · CVE-2026-33001
**Name of the Vulnerable Software and Affected Versions**
Jenkins versions 2.554 and earlier
Jenkins LTS versions 2.541.2 and earlier
**Description**
The software does not safely handle symbolic links when extracting .tar and .tar.gz archives. This allows crafted archives to write files to arbitrary locations on the filesystem, limited by the file system access permissions of the user running Jenkins. An attacker with Item/Configure permission, or control over agent processes, can exploit this to deploy malicious scripts or plugins on the controller.
**Recommendations**
Update Jenkins to a version later than 2.554.
Update Jenkins LTS to a version later than 2.541.2.
