Description

Jenkins Credentials Binding Plugin has a path traversal vulnerability

Jenkins Credentials Binding Plugin versions 719.v80e905ef14eb_ and earlier do not sanitize file names for file and zip file credentials.

This allows attackers able to provide credentials to a job to write files to arbitrary locations on the node filesystem. 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, this can lead to remote code execution.

Credentials Binding Plugin 720.v3f6decef43ea_ sanitizes the file name provided for file and zip file credentials, preventing path traversal.

How this vulnerability can be exploited

This issue can be reached over the network, attack complexity is high, an attacker needs low-level privileges on the target. No user interaction is required. The scope is unchanged, so the impact stays within the vulnerable component. Rated impact: confidentiality high, integrity high, availability high.

Weakness class

CVE-2026-42520 is classified as CWE-22: Path Traversal. A file path built from user input is not confined to the intended directory, letting an attacker reach files elsewhere on the filesystem.
