Modula Image Gallery – Photo Grid & Video Gallery

The Modula Image Gallery – Photo Grid & Video Gallery plugin for WordPress is vulnerable to PHP Object Injection in versions up to, and including, 2.14.18 via deserialization of untrusted input. This makes it possible for authenticated attackers, with author-level access and above, to inject a PHP Object. No known POP chain is present in the vulnerable software. If a POP chain is present via an additional plugin or theme installed on the target system, it could allow the attacker to delete arbitrary files, retrieve sensitive data, or execute code.

The Modula Image Gallery – Photo Grid & Video Gallery plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 2.13.6. This is due to the plugin not properly verifying that a user is authorized to modify specific posts before updating them via the REST API. This makes it possible for authenticated attackers, with contributor level access and above, to update the title, excerpt, and content of arbitrary posts by passing post IDs in the modulaImages field when editing a gallery.

The Modula Image Gallery plugin for WordPress is vulnerable to Stored Cross-Site Scripting in versions up to, and including, 2.13.4 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with author-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

The Image Gallery – Photo Grid & Video Gallery plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the `add_images_to_gallery_callback()` function in all versions up to, and including, 2.13.3. This makes it possible for authenticated attackers, with Author-level access and above, to add images to arbitrary Modula galleries owned by other users.

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.

The Modula Image Gallery plugin for WordPress is vulnerable to arbitrary file uploads due to missing file type validation in the 'ajax_unzip_file' function in versions 2.13.1 to 2.13.2. This makes it possible for authenticated attackers, with Author-level access and above, to upload arbitrary files with race condition on the affected site's server which may make remote code execution possible.

The Modula Image Gallery plugin for WordPress is vulnerable to arbitrary file deletion due to insufficient file path validation in the 'ajax_unzip_file' function in versions 2.13.1 to 2.13.2. This makes it possible for authenticated attackers, with Author-level access and above, to delete arbitrary files on the server, which can easily lead to remote code execution when the right file is deleted (such as wp-config.php).

The Modula Image Gallery – Photo Grid & Video Gallery plugin for WordPress is vulnerable to unauthorized access due to a missing capability check on a function in all versions up to, and including, 2.13.6. This makes it possible for authenticated attackers, with Subscriber-level access and above, to perform an unauthorized action.

The Image Gallery – Photo Grid & Video Gallery plugin for WordPress is vulnerable to arbitrary file deletion due to insufficient file path validation in the ajax_import_file function in all versions up to, and including, 2.12.28. This makes it possible for authenticated attackers, with author-level access and above, to move arbitrary image files on the server.
