CVE-2025-13891

35th percentile - higher than 35% of all known CVEs

The Image Gallery – Photo Grid & Video Gallery plugin for WordPress is vulnerable to Path Traversal in all versions up to, and including, 2.13.3. This is due to the modula_list_folders AJAX endpoint that lacks proper path validation and base directory restrictions. While the endpoint verifies user capabilities (Author+ with upload_files and edit_posts permissions), it fails to validate that user-supplied directory paths reside within safe directories. This makes it possible for authenticated attackers, with Author-level access and above, to enumerate arbitrary directories on the server via the modula_list_folders endpoint.

An authenticated attacker with Author-level access can enumerate arbitrary directories on the server, potentially revealing the file system structure and sensitive information. This may facilitate further attacks such as file reading or privilege escalation.

Update the Image Gallery plugin to a version later than 2.13.3 that contains the fix. Until then, restrict access to the modula_list_folders endpoint or disable the plugin if not in use.
