CVE-2026-39481

The Modula Image Gallery plugin for WordPress (versions up to and including 3.0.11) is vulnerable to sensitive information exposure via the 'id' parameter in /wp-json/wp/v2/modula-gallery/{id}. An unauthenticated attacker can extract the plaintext Password Protect password and username for every published gallery from the modulaSettings REST field.

The Modula Image Gallery plugin for WordPress contains a missing authorization vulnerability that allows retrieving embedded sensitive data. The issue affects versions up to and including 3.0.11.

The Modula Image Gallery plugin versions 2.14.25 through 2.14.30 are vulnerable to stored XSS attacks. An attacker can inject a malicious script that executes in other users' browsers.

There is a Subscriber Cross Site Scripting (XSS) vulnerability in Modula Image Gallery versions up to 2.14.23.

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).
