Meta Box <= 5.11.1 - Arbitrary File Deletion

id: CVE-2026-39468

info:
  name: Meta Box <= 5.11.1 - Arbitrary File Deletion
  author: iamatownboy
  severity: high
  description: |
    The Meta Box plugin for WordPress is vulnerable to arbitrary file deletion due to insufficient file path validation in the ajax_delete_file function. This makes it possible for authenticated attackers with Contributor-level access and above to delete arbitrary files on the server.
  impact: |
    Authenticated attackers can delete arbitrary files such as wp-config.php, which can lead to remote code execution in the right configuration.
  remediation: |
    Update Meta Box to version 5.11.2 or later.
