CVE-2026-12435

Popis

The Motors – Car Dealership & Classified Listings Plugin plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 1.4.111. This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for authenticated attackers, with subscriber-level access and above, to mark or unmark any other user-s car listing as sold by replaying a valid nonce harvested from their own listing against an arbitrary victim post ID, triggering a site-wide -Sold- badge on the victim-s listing and silently stripping its special_car featured post meta as a side effect. Exploitation requires the attacker to hold an active listing of their own (obtainable by a Subscriber via the plugin-s add-listing form) in order to harvest a valid nonce for the -stm_mark_as_sold_car- action, which can then be replayed against any other listing-s post ID.
