The PeproDev Ultimate Profile Solutions plugin for WordPress is vulnerable to unauthorized access of data via its publicly exposed reset-password endpoint. The plugin looks up the 'valid_email' value based solely on a supplied username parameter, without verifying that the requester is associated with that user account. This allows unauthenticated attackers to enumerate email addresses for any user, including administrators.
The product does not perform or incorrectly performs an authorization check when an actor attempts to access a resource or perform an action.
