CVE-2026-15384

Last modified

CVE-2026-15384 is a medium-severity vulnerability rated 5.7/10 on the CVSS scale. 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. EPSS estimates a 0.11% chance of exploitation in the next 30 days.

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.
