📄 Description (English)
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.
🤖 AI Executive Summary
The Ultimate Member WordPress plugin (versions ≤2.11.2) contains a critical authentication bypass vulnerability allowing authenticated attackers with Contributor access to generate valid password reset tokens for higher-privileged users (including Administrators) through malicious post previews. This enables full account takeover of administrative accounts and potential complete WordPress installation compromise. The vulnerability requires no exploit code and poses immediate risk to Saudi organizations using this plugin.

4. Enable multi-factor authentication (MFA) for all Administrator accounts
5. Implement IP whitelisting for administrative access
6. Deploy file integrity monitoring on wp-content/plugins/ultimate-member/ directory
DETECTION RULES:
1. Monitor WordPress logs for post preview actions by Contributor-level users
2. Alert on password reset token generation events followed by external HTTP requests
3. Monitor wp_usermeta table for suspicious password_reset_link entries
4. Track failed login attempts followed by successful logins from different IP addresses
5. Monitor for unauthorized administrative user creation or privilege escalation
