Name of the Vulnerable Software and Affected Versions WP User plugin for WordPress versions up to, and including, 7.0

Description The issue is related to Stored Cross-Site Scripting via the plugin's settings parameters due to insufficient input sanitization and output escaping. This allows authenticated attackers with administrator-level permissions and above to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. The issue only affects multi-site installations and installations where unfiltered html has been disabled.

Recommendations For WP User plugin for WordPress versions up to, and including, 7.0, update to a version that addresses the insufficient input sanitization and output escaping issue. As a temporary workaround, consider restricting access to the settings parameters to minimize the risk of exploitation. Additionally, ensure that unfiltered html is enabled, if possible, to reduce the attack surface.
