CVE-2024-8519 Information

Description

The Ultimate Member – User Profile Registration Login Member Directory Content Restriction & Membership Plugin plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin’s ‘um_loggedin’ shortcode in all versions up to and including 2.8.6 due to insufficient input sanitization and output escaping on user supplied attributes. This makes it possible for authenticated attackers with contributor-level access and above to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
