Summary

WP User Manager for WordPress is affected in all versions up to and including 2.10.2. Insufficient input sanitization and output escaping of the display_name user field allow stored cross-site scripting (CWE-79). An authenticated attacker with subscriber-level access or above can inject web scripts that run in a user's browser when that user opens an affected page. The WordPress core REST users endpoint stores the value without the plugin's sanitizer, so the plugin's save-time sanitization does not mitigate the flaw.

Description from the CNA

The WP User Manager – Registration Form, Login Form, User Profile Builder & Member Directory plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'name (REST users endpoint) -> wp_users.display_name' parameter in all versions up to, and including, 2.10.2 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. The payload is stored via the WordPress core REST endpoint POST /wp-json/wp/v2/users/me, which bypasses the plugin's own wpum_sanitize_text sanitizer applied on its front-end account form, making the save-time sanitization ineffective as a mitigation.
