CVE-2026-4977
Last modified
CVE-2026-4977 is a medium-severity vulnerability rated 4.3/10 on the CVSS scale. The UsersWP – Front-end login form, User Registration, User Profile & Members Directory plugin for WordPress is vulnerable to Improper Access Control in all versions up to, and including, 1.2.58 This is due to insufficient field-level permission validation in the upload_file_remove() AJAX handler where the $htmlvar parameter is not validated against a whitelist of allowed fields or checked against the field's for_admin_use property. This makes it possible for authenticated attackers, with subscriber-level access and above, to clear or reset any restricted usermeta column for their own user record, including fields marked as "For admin use only", bypassing intended field-level access restrictions.. EPSS estimates a 0.30% chance of exploitation in the next 30 days.
