Summary
The Ultimate Member plugin for WordPress is affected in all versions up to and including 2.14.0. The 'user_url' profile field is not sanitized or escaped on input or output, which is a cross-site scripting flaw (CWE-79). An authenticated attacker with subscriber-level access or above can inject arbitrary web scripts that run when a visitor clicks the Website URL link on the attacker's public profile.

Description from the CNA
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 'user_url' parameter in all versions up to, and including, 2.14.0 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. Successful exploitation requires a visitor to click the attacker's Website URL link on their public Ultimate Member profile, a condition that is trivially met since the redirect-confirmation onclick handler is enabled by default on all new installations.
