Jenkins Command Line Interface (CLI) Path Traversal Vulnerability (CVE-2024-23897)

A remote attacker, without authentication, can achieve full data confidentiality loss, arbitrary modification of data, complete denial of service or system unavailability. CISA has confirmed use of this vulnerability in known ransomware campaigns — treat as high priority for remediation. Federal agencies are required to remediate by 2024-09-09 under CISA BOD 22-01.

This is a Path Traversal (CWE-22) vulnerability in Jenkins Jenkins Command Line Interface (CLI). 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. Exploitation requires remote network access, low attack complexity, no authentication required, and no user interaction required.

Probably yes if any of these apply:
