CVE-2026-4248 - Ultimate Member <= 2.11.2 - Authenticated (Contributor+) Sensitive Information Exposure to Account Takeover via Shortcode Template Tag
CVE ID :CVE-2026-4248
Published : March 27, 2026, 11:17 p.m. | 1 hour, 48 minutes ago
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.
Severity: 8.0 | HIGH
