Name of the Vulnerable Software and Affected Versions:

Mmm Unity Loader plugin for WordPress versions prior to 1.0

Description:

The Mmm Unity Loader plugin for WordPress is susceptible to Stored Cross-Site Scripting via the `attributes` parameter due to insufficient input sanitization and output escaping. This allows authenticated attackers with Contributor-level access or higher to inject arbitrary web scripts into pages. These scripts will execute when a user accesses the injected page.

Recommendations:

Update the Mmm Unity Loader plugin to a version later than 1.0.
