Description
The Passster – Password Protect Pages and Content plugin for WordPress is vulnerable to Sensitive Information Exposure via the comments of password-locked posts in all versions up to, and including, 4.3.20, due to the plugin not restricting comment lists, comment feeds, comment counts and the REST API comments endpoints for posts the visitor has not unlocked. This makes it possible for unauthenticated attackers to read the comments of locked posts and to post comments on them without knowing the password.
