## What is CVE-2026-1254?

CVE-2026-1254 is a medium-severity missing authorization vulnerability in wpchill Modula Image Gallery – Photo Grid & Video Gallery, published on 14 Feb 2026. Any signed-in user can exploit it over the network, with no action from the victim.

### Official description

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.
