CVE-2026-10779
CWE-862Published: June 19, 2026· Updated: Jun 22, 2026
Official Description
The Classified Listing – Classified ads & Business Directory plugin for WordPress is vulnerable to Missing Authorization in all versions up to, and including, 5.4.2. This is due to a missing capability/ownership check on the gallery_image_update_as_feature AJAX handler (action: rtcl_fb_gallery_image_update_as_feature), which accepts a user-supplied listing ID and attachment ID and sets the featured image of a listing while only validating a nonce that is exposed to any logged-in user on the frontend listing-submission form. This makes it possible for authenticated attackers, with Subscriber-level access and above, to change the featured image of arbitrary listings they do not own.
Technical Analysis
CVE-2026-10779 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.
Exploitation requires low privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
