Name of the Vulnerable Software and Affected Versions: The Ultimate Member – User Profile, Registration, Login, Member Directory, Content Restriction & Membership Plugin plugin for WordPress versions up to, and including, 2.8.6

Description: The issue is related to Stored Cross-Site Scripting via the plugin's 'um loggedin' shortcode due to insufficient input sanitization and output escaping on user-supplied attributes. This allows 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.

Recommendations: For versions up to, and including, 2.8.6, update to a version higher than 2.8.6 to resolve the issue. As a temporary workaround, consider restricting access to the 'um loggedin' shortcode until a patch is available. Additionally, restrict contributor-level access and above to minimize the risk of exploitation.
