Official Description

Jenkins Credentials Binding Plugin 719.v80e905ef14eb_ and earlier does not sanitize file names for file and zip file credentials, allowing attackers able to provide credentials to a job to write files to arbitrary locations on the node filesystem, which can lead to remote code execution if Jenkins is configured to allow a low-privileged user to configure file or zip file credentials used for a job running on the built-in node.

Technical Analysis

CVE-2026-42520 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.

Exploitation requires low privileges, which limits the exposure to scenarios where an attacker has already gained initial access.

A successful exploit results in complete confidentiality breach (data exposure), full integrity compromise (data manipulation), availability disruption (denial of service), with a CVSS base score of 7.5.
