Image Gallery – Photo Grid & Video Gallery (Modula) <= 2.13.3 - Missing Authorization to Arbitrary Directory Listing

Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')
CVE CVE-2025-13891
CVSS Medium (6.5)
Publicly Published December 11, 2025
Last Updated December 12, 2025
Researcher Dmitrii Ignatyev
Description

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.
