Ultimate Member – User Profile, Registration, Login, Member Directory, Content Restriction & Membership Plugin, CVE-2026-4248
- CVE, Research URL
- Published on
- Mar 28, 2026
- Research Description
- The Ultimate Member plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 2.11.2. This is due to the '{usermeta:password_reset_link}' template tag being processed within post content via the '[um_loggedin]' shortcode, which generates a valid password reset token for the currently logged-in user viewing the page. This makes it possible for authenticated attackers, with Contributor-level access and above, to craft a malicious pending post that, when previewed by an Administrator, generates a password reset token for the Administrator and exfiltrates it to an attacker-controlled server, leading to full account takeover.
- Affected versions

max 2.11.3.
