The Import and export users and customers plugin for WordPress is vulnerable to privilege escalation in all versions up to, and including, 1.29.7. This is due to the 'save extra user profile fields' function not properly restricting which user meta keys can be updated via profile fields. The 'get restricted fields' method does not include sensitive meta keys such as 'wp capabilities'. This makes it possible for unauthenticated attackers to escalate their privileges to Administrator by submitting a crafted registration request that sets the 'wp capabilities' meta key. The vulnerability can only be exploited if the "Show fields in profile" setting is enabled and a CSV with a wp capabilities column header has been previously imported.
