Summary
The Motors – Car Dealership & Classified Listings plugin for WordPress up to version 1.4.111 is vulnerable to authorization bypass. An authenticated attacker with subscriber-level access can mark or unmark any other user's car listing as sold by replaying a valid nonce from their own listing.
Risk Assessment
Attackers can tamper with the sold status of other users' listings without authorization, leading to fraud, loss of trust, and potential financial harm to sellers.
Recommendation
Immediately update the Motors – Car Dealership & Classified Listings plugin to the latest patched version. If no update is available, temporarily disable the plugin or restrict access to the mark-as-sold functionality.
Other vulnerabilities in Motors – Car Dealership & Classified Listings Plugin
See all- CVE-2026-6806High
The Motors – Car Dealership & Classified Listings Plugin plugin for WordPress is vulnerable to time-based blind SQL Injection via the 'stm_lat/stm_lng' parameter in all versions up to, and including, 1.4.109 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for unauthenticated attackers to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.
- CVE-2026-96563Medium
The Motors – Car Dealership & Classified Listings plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'stm_f_s' parameter in all versions up to, and including, 1.4.124 due to insufficient input sanitization and output escaping. Authenticated attackers with subscriber-level access and above can inject arbitrary web scripts that execute when a user accesses an injected page; the nonce required by the stm_ajax_add_a_car AJAX handler is emitted in wp_footer on every page, making it accessible to any authenticated user.
- CVE-2026-16750Medium
The Motors – Car Dealership & Classified Listings Plugin for WordPress is vulnerable to unauthorized access of data due to missing authorization checks in mvl_ajax_dealer_load_cars() function in all versions up to, and including, 1.4.120. This makes it possible for unauthenticated attackers to retrieve draft, pending, private, and future car listings belonging to arbitrary users.
- CVE-2026-13114High

Original NVD description (English source)
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.
