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:passwordresetlink}' template tag being processed within post content via the '[umloggedin]' 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.
WordPress Plugin ultimate-member 2.1.3 contains a local file inclusion vulnerability that allows authenticated attackers to include arbitrary files by manipulating the pack parameter in class-admin-upgrade.php. Attackers can send POST requests with malicious pack values to include unintended PHP files from the packages directory and execute arbitrary code.
