CVE-2025-13646: Wpchill Modula Image Gallery

Medium severity, CVSS 6.6. EPSS: 0.8% chance of exploitation in the next 30 days.

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.

Affected products

• Wpchill Modula Image Gallery: from 2.13.1, before 2.13.3 (fixed in 2.13.3)
