## What is CVE-2026-15384?

CVE-2026-15384 is a medium-severity missing authorization vulnerability in Unknown Manual Image Crop, published on 16 Aug 2026. Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.

### Official description

The Manual Image Crop WordPress plugin before 1.15 does not perform any capability check or nonce verification on the authenticated AJAX action that crops attachment images; its only guard passes for any logged-in user. A subscriber-level user can therefore supply an arbitrary attachment ID and overwrite that attachment's generated intermediate-size image (for example its thumbnail) and mutate its stored metadata, regardless of who owns the media. This is a cross-user integrity/defacement issue over the Media Library. The action also has no nonce, so it is additionally susceptible to CSRF.

Weakness: CWE-352 (Cross-Site Request Forgery), CWE-287 (Improper Authentication)
