Deferred Deferred - Pending Action

Stored XSS in The Motors WordPress Plugin

Publication date: 2026-11-07

Last updated on: 2026-11-07

Assigner: Wordfence

Description
The Motors – Car Dealership & Classified Listings Plugin plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'stm_f_s[make]' parameter in all versions up to, and including, 1.4.128 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with subscriber-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This requires the Free Listing Submission feature to be enabled, which is shipped on by default via the Setup Wizard demo configuration.

Executive Summary

This vulnerability is a Stored Cross-Site Scripting (XSS) flaw in the Motors – Car Dealership & Classified Listings Plugin for WordPress. It exists due to insufficient input sanitization and output escaping in the 'stm_f_s[make]' parameter. Authenticated attackers with subscriber-level access or higher can inject malicious scripts into pages. The Free Listing Submission feature must be enabled, which is active by default.

Detection Guidance

This vulnerability requires checking WordPress sites using the Motors plugin for vulnerable versions. Inspect plugin files for the 'stm_f_s[make]' parameter usage and verify input sanitization. Check WordPress admin for plugin version under 1.4.128. Enable debug logs to monitor suspicious script injections.

Impact Analysis

An attacker could inject malicious scripts into pages viewed by other users. This could lead to unauthorized actions on behalf of users, theft of session cookies, or defacement of the website. The impact depends on user privileges and the extent of the attack.

Compliance Impact

This vulnerability could lead to unauthorized access or data breaches, violating GDPR and HIPAA requirements for data protection and user privacy. Organizations may face legal penalties, reputational damage, and loss of customer trust if exploited.

Mitigation Strategies

Update the Motors – Car Dealership & Classified Listings Plugin to the latest version, which is beyond 1.4.128, to address the Stored Cross-Site Scripting vulnerability. Disable the Free Listing Submission feature if not needed, as it is enabled by default and contributes to the risk.
