CVE-2026-10779Network attack vector

Subscriber-level listing defacement via unchecked ownership

Published Jun 19, 2026 · Updated Jun 19, 2026

Missing authorization in RadiusTheme Classified Listing 5.4.2 and earlier allows remote authenticated users to alter arbitrary listing images. The gallery_image_update_as_feature AJAX handler trusts user-supplied listing and attachment IDs after checking only a frontend nonce, without verifying capability or listing ownership. Subscriber-level access and the exposed submission-form nonce are sufficient to replace another owner's featured image, enabling content defacement.
