# WordPress Motors car plugin: stored script injection via make filter

Link for people: https://infrastack.ai/live/CVE-2026-116562 (this .md is for agents)

The Motors car dealership plugin for WordPress does not sanitize the 'stm_f_s[make]' parameter, so a logged-in subscriber can store a script on a page. The script runs in the browser of anyone who opens that page, including administrators.

_Summary, check and fix written by a model from the sources; labelled as such._

## How to check

- Check the installed Motors plugin version in the WordPress admin plugin list; versions up to and including `1.4.128` are listed as affected.
- Check whether the Free Listing Submission feature is enabled in the plugin settings.

## Fix

- Motors plugin: unknown (sources do not name a fixed version)

## Timeline

- 2026-11-07T03:45:32+00:00 nvd https://nvd.nist.gov/vuln/detail/CVE-2026-116562

## From the sources

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.
