The Ultimate Member plugin for WordPress, which manages user profiles and membership access, contains a stored cross-site scripting vulnerability in the user profile URL field.

The vulnerability affects all versions up to 2.14.0 and requires the attacker to be a subscriber or higher with a trivial social engineering trigger.

Upgrade to version 2.14.1 or later. The fix adds a confirmation prompt for external links and improves input handling for the user_url parameter.

## Technical details

Insufficient input sanitization and output escaping of the 'user_url' parameter allows authenticated attackers with subscriber-level access to inject stored XSS payloads. The vulnerability is made practical by a default redirect-confirmation onclick handler that triggers when users click the external link on a public profile. An attacker can store malicious JavaScript that executes in the context of any visitor viewing the compromised profile.
