Privilege Escalation in WordPress Import and export users and customers Plugin
CVE-2026-3629 is a privilege escalation vulnerability in the WordPress plugin Import and export users and customers affecting all versions up to and including 1.29.7. The flaw is caused by the save_extra_user_profile_fields function failing to properly restrict which user meta keys may be updated through profile fields. Specifically, the plugin's get_restricted_fields method does not block sensitive meta keys such as wp_capabilities. As a result, an attacker can submit a crafted registration request that sets wp_capabilities and thereby assign elevated privileges to the created account. Based on the provided information, exploitation is possible without authentication when the plugin is configured to expose profile fields and when a CSV containing a wp_capabilities column header has previously been imported.
