The WP EXtra plugin for WordPress is vulnerable to unauthorized access to restricted functionality due to a missing capability check on the 'test-email' section of the register() function in versions up to, and including, 6.2. This makes it possible for authenticated attackers, with minimal permissions such as a subscriber, to send emails with arbitrary content to arbitrary locations from the affected site's mail server.
Default status is the baseline for the product, each version can override it (e.g. patched versions marked unaffected).
