CVE-2025-12154 High · 8.8 CWE-434 Dec 5, 2025

Auto Thumbnailer <= 1.0 - Authenticated (Contributor+) Arbitrary File Upload

The Auto Thumbnailer plugin for WordPress is vulnerable to arbitrary file uploads due to missing file type validation in the uploadThumb() function in all versions up to, and including, 1.0. This makes it possible for authenticated attackers, with Contributor-level access and above, to upload arbitrary files on the affected site's server which may make remote code execution possible.
