{"id":"CVE-2026-12435","state":"PUBLISHED","title":"Motors <= 1.4.111 - Missing Authorization to Authenticated (Subscriber+) Arbitrary Post Meta Modification via 'stm_mark_as_sold_car' Parameter","description":"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.","publishedAt":"2026-07-01T07:53:36.717Z","updatedAt":"2026-07-01T10:32:04.521Z","severity":{"score":4.3,"label":"Medium","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N","source":"Wordfence"},"assigner":"Wordfence","products":["stylemix Motors – Car Dealership & Classified Listings Plugin"],"affected":[{"vendor":"stylemix","product":"Motors – Car Dealership & Classified Listings Plugin","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"1.4.111","versionType":"semver"}]}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/5238c344-d685-4eab-822c-d3c1050cc982?source=cve","https://plugins.trac.wordpress.org/browser/motors-car-dealership-classified-listings/tags/1.4.110/includes/vehicle_functions.php#L2402","https://plugins.trac.wordpress.org/browser/motors-car-dealership-classified-listings/tags/1.4.110/includes/vehicle_functions.php#L2400","https://plugins.trac.wordpress.org/browser/motors-car-dealership-classified-listings/tags/1.4.110/templates/listing-cars/listing-list-owner-actions.php#L74","https://plugins.trac.wordpress.org/browser/motors-car-dealership-classified-listings/tags/1.4.108/includes/vehicle_functions.php#L2402","https://plugins.trac.wordpress.org/browser/motors-car-dealership-classified-listings/tags/1.4.108/includes/vehicle_functions.php#L2400","https://plugins.trac.wordpress.org/browser/motors-car-dealership-classified-listings/tags/1.4.108/templates/listing-cars/listing-list-owner-actions.php#L74","https://plugins.trac.wordpress.org/changeset?sfp_email=&sfph_mail=&reponame=&old=3577332%40motors-car-dealership-classified-listings&new=3577332%40motors-car-dealership-classified-listings&sfp_email=&sfph_mail="],"weaknesses":["CWE-862"],"ingestedAt":"2026-10-29T20:10:52.580Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/12xxx/CVE-2026-12435.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-12435","state":"PUBLISHED","datePublished":"2026-07-01T07:53:36.717Z","dateUpdated":"2026-07-01T10:32:04.521Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2026-06-16T18:34:03.436Z"},"containers":{"cna":{"title":"Motors <= 1.4.111 - Missing Authorization to Authenticated (Subscriber+) Arbitrary Post Meta Modification via 'stm_mark_as_sold_car' Parameter","descriptions":[{"lang":"en","value":"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.
