CVE-2026-42520 is a high-severity vulnerability rated 7.5/10 on the CVSS scale. 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.. EPSS estimates a 0.41% chance of exploitation in the next 30 days.
