Name of the Vulnerable Software and Affected Versions WP Cleanup and Basic Functions plugin for WordPress versions up to, and including, 2.2.1

Description The issue is related to Stored Cross-Site Scripting via SVG File uploads due to insufficient input sanitization and output escaping. This allows authenticated attackers with Author-level access and above to inject arbitrary web scripts in pages that will execute whenever a user accesses the SVG file.

Recommendations For versions up to, and including, 2.2.1, consider disabling SVG file uploads until a patch is available to prevent exploitation. Restrict access to the plugin's functionality to minimize the risk of arbitrary web script injection. Update to a version that addresses the insufficient input sanitization and output escaping issues.
