Summary
The Ultimate Member plugin for WordPress up to version 2.11.1 is vulnerable to stored cross-site scripting (XSS) via the user description field due to insufficient input sanitization and output escaping. Authenticated attackers with subscriber-level access or higher can inject arbitrary scripts that execute when a user visits an affected page. The vulnerability is exploitable only when "HTML support for user description" is enabled in Ultimate Member settings.
Risk Assessment
An authenticated attacker can inject a malicious script that executes in other users' browsers, leading to session theft, redirects, or data theft.
Recommendation
Immediately update the Ultimate Member plugin to version 2.11.2 or later. If an update is not possible, disable the "HTML support for user description" option in the plugin settings.
