Is Modula Image Gallery safe? Known vulnerabilities and latest version

The Modula Image Gallery – Photo Grid & Video Gallery plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 3.0.11 via the 'id (post ID in /wp-json/wp/v2/modula-gallery/{id}) or none for collection route' parameter. This makes it possible for unauthenticated attackers to extract the plaintext Password Protect password and username for every published gallery from the modulaSettings REST field. The plugin's own /wp-json/modula/v2/gallery/{id}/settings endpoint correctly redacts the password for unauthenticated callers via redact_settings_for_public(), but no equivalent redaction is applied on the core /wp-json/wp/v2/modula-gallery path exposed by show_in_rest=true CPT registration.

Missing Authorization vulnerability in WP Chill Modula Image Gallery modula-best-grid-gallery allows Retrieve Embedded Sensitive Data.This issue affects Modula Image Gallery: from n/a through 3.0.11.

The Modula Image Gallery – Photo Grid & Video Gallery plugin for WordPress is vulnerable to arbitrary file deletion due to insufficient file path validation in the upload_image function in all versions up to, and including, 3.0.2. This makes it possible for authenticated attackers, with author-level access and above, to delete arbitrary files on the server. The path restriction to wp-content/uploads is not an effective ownership boundary, as all user attachment files reside within that tree, and Authors trivially satisfy the edit_post check on their own galleries.

The Modula Image Gallery – Photo Grid & Video Gallery plugin for WordPress is vulnerable to unauthorized disclosure of private gallery contents in versions up to, and including, 3.0.1. This is due to the Modula_Meta::add_metas() function being hooked to wp_head on every frontend request and looking up any post via get_post( $_GET['modula_gallery_id'] ) without verifying the gallery's post_status or the requester's capability to read it — the gallery-side input guard is bugged (empty('modula_gallery_id') tests a nonempty string literal instead of the GET parameter, so it is always false), the only object validation is a post_type === 'modula-gallery' check, and no is_user_logged_in()/current_user_can('read_post', $gallery_id) check is performed. This makes it possible for unauthenticated attackers to enumerate private modula-gallery posts and their member attachments and recover the image's title, description, dimensions, and original upload URL via Open Graph/Twitter meta tags emitted in the response, which then allows direct unauthenticated download of the original private image bytes.

Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in WP Chill Modula Image Gallery allows Stored XSS. This issue affects Modula Image Gallery: from 2.14.25 through 2.14.30.

Subscriber Cross Site Scripting (XSS) in Modula Image Gallery <= 2.14.23 versions.

Author PHP Object Injection in Modula Image Gallery <= 2.14.18 versions.

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.

Missing Authorization vulnerability in WP Chill Modula Image Gallery modula-best-grid-gallery allows Exploiting Incorrectly Configured Access Control Security Levels.This issue affects Modula Image Gallery: from n/a through <= 2.13.6.

Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in WP Chill Modula Image Gallery modula-best-grid-gallery allows Stored XSS.This issue affects Modula Image Gallery: from n/a through <= 2.13.4.

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 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.

The Modula Image Gallery plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's bundled FancyBox JavaScript library (versions <= 5.0.36) due to insufficient input sanitization and output escaping on user supplied attributes. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

The Modula Image Gallery plugin for WordPress is vulnerable to arbitrary file uploads due to missing file type validation in the zip upload functionality in all versions up to, and including, 2.11.10. This makes it possible for authenticated attackers, with Author-level access and above, to upload arbitrary files on the affected site's server which may make remote code execution possible.

Unauth. Plugin Settings Change vulnerability in Modula plugin <= 2.6.9 on WordPress.

A stored XSS vulnerability exists in the Modula Image Gallery plugin before 2.2.5 for WordPress. Successful exploitation of this vulnerability would allow an authenticated low-privileged user to inject arbitrary JavaScript code that is viewed by other users.
