CVE-2026-107625

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.
