CVE-2026-6566

Estado: AplazadaMedia (4.3)—

The Photo Gallery, Sliders, Proofing and Themes – NextGEN Gallery plugin for WordPress is vulnerable to Insecure Direct Object Reference in versions up to and including 4.2.0. This is due to insufficient object-level authorization in the image deletion REST flow where the permission callback for DELETE /imagely/v1/images/{id} only checks 'NextGEN Manage gallery' permissions and does not enforce gallery ownership or 'NextGEN Manage others gallery' permissions. This makes it possible for authenticated attackers, with Subscriber-level privileges and 'NextGEN Manage gallery' capability, to delete gallery images belonging to other users as well as their associated image files from disk when deleteImg is enabled (default).

Esto hace posible que atacantes autenticados, con privilegios de nivel de Suscriptor y la capacidad 'NextGEN Manage gallery', eliminen imágenes de la galería pertenecientes a otros usuarios, así como sus archivos de imagen asociados del disco cuando deleteImg está habilitado (por defecto)."
