Jenkins Command Line Interface (CLI) Path Traversal Vulnerability

Published Jan 24, 2024 · corrected/updated Jun 17, 2026 · Jenkins Jenkins Command Line Interface (CLI) · evidence confidence very high

Jenkins 2.441 and earlier, LTS 2.426.2 and earlier does not disable a feature of its CLI command parser that replaces an '@' character followed by a file path in an argument with the file's contents, allowing unauthenticated attackers to read arbitrary files on the Jenkins controller file system.

Grounded briefings

Catalog interpretations for three audiences. Each brief cites ingested metadata and the original advisories below. They are not independent research and they do not invent exploit steps.

Executive

CVE-2024-23897 is a critical public vulnerability record for Jenkins Jenkins Command Line Interface (CLI). CISA lists it as known exploited.
