CVE-2026-116617 Motors <= 1.4.128 - Authenticated (Subscriber+) File Deletion via 'stm_dealer_logo_path' Parameter

Description

The Motors – Car Dealership & Classified Listings Plugin plugin for WordPress is vulnerable to File Deletion in all versions up to, and including, 1.4.128 The vulnerability exists because `stm_save_user_extra_fields()`, hooked to `personal_options_update`, writes the attacker-controlled `stm_dealer_logo_path` parameter directly to user meta without an ownership check binding the submitted path to the submitting user — unlike the `stm_payment_status` and `stm_lost_password_hash` fields, this field is not gated by a `manage_options` or `edit_users` capability check. This makes it possible for authenticated attackers, with Subscriber-level access and above, to delete image files belonging to other users under `wp-content/uploads` — including other users' avatars, dealer logos, and uploaded media — by storing a crafted path via their own profile and then triggering `unlink()` through the become-dealer form on their author page. Note that the two path guards (`stm_mvl_is_path_within_uploads` and `stm_mvl_is_allowed_image_file`) do restrict the attack surface to files with an image extension that resolve within the uploads basedir; files outside that directory, such as `wp-config.php` or plugin PHP files, cannot be reached.

Exploitable à distance par le réseau, avec un compte ordinaire et sans action d’un utilisateur ; un attaquant peut compromettre gravement la confidentialité, l’intégrité ou la disponibilité.
