What is CVE-2025-12957?
CVE-2025-12957 is a high-severity vulnerability in plugins360 All-in-One Video Gallery, published on 16 Jan 2026. Any signed-in user can exploit it over the network, with no action from the victim.
Official description
The All-in-One Video Gallery plugin for WordPress is vulnerable to arbitrary file upload in all versions up to, and including, 4.5.7. This is due to insufficient file type validation detecting VTT files, allowing double extension files to bypass sanitization while being accepted as a valid VTT file. 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.
Weakness: CWE-434
