CVE-2026-104746 is not in CISA's Known Exploited Vulnerabilities (KEV) catalog. No public exploit code is tracked. It is rated CVSS 8.1 (high) and affects Motors – Car Dealership & Classified Listings Plugin; no fixed version is listed yet.

## Summary

Motors, a WordPress car dealership and classified listings plugin, contains a flaw in versions up to and including 1.4.125 that lets a logged-in user with basic Subscriber access delete arbitrary files within the wp-content/uploads directory over the network. Deleting the right file in that location could help an attacker take further control of the site.

Model-written summary (anthropic/claude-haiku-5.5). Verify details against the original sources.

## Affected

- stylemix Motors – Car Dealership & Classified Listings Plugin: through 1.4.125

## Description

The Motors – Car Dealership & Classified Listings Plugin plugin for WordPress is vulnerable to arbitrary file deletion due to insufficient file path validation in the stm_listings_ajax_save_user_data function in all versions up to, and including, 1.4.125 This makes it possible for authenticated attackers, with subscriber-level access and above, to delete arbitrary files on the server, which can easily lead to remote code execution when the right file is deleted (such as wp-config.php). Although deletion is bounded to wp-content/uploads (preventing removal of wp-config.php), any authenticated Subscriber can trivially exploit this because the required AJAX nonce is printed on every front-end page and the handler's stm_user_avatar_path meta is writable by any logged-in user against their own account.
