Jenkins · Jenkins · CVE-2026-33001
**Name of the Vulnerable Software and Affected Versions**
Jenkins versions prior to 2.555
Jenkins LTS versions prior to 2.541.3
**Description**
Unsafe handling of symbolic links during the extraction of .tar and .tar.gz archives allows attackers with Item/Configure permission, or those who can control agent processes, to write files to arbitrary locations on the filesystem. This action is restricted only by the file system access permissions of the user running Jenkins. Such a flaw could enable the deployment of malicious scripts or plugins on the Jenkins controller, potentially leading to unauthorized code execution.
**Recommendations**
Update Jenkins to version 2.555 or later.
Update Jenkins LTS to version 2.541.3 or later.
