What the vulnerability does
01Description
The Truelysell Core plugin for WordPress is vulnerable to Arbitrary User Password Change in versions up to, and including, 1.8.6. This is due to the plugin providing user-controlled access to objects, letting a user bypass authorization and access system resources. This makes it possible for unauthenticated attackers to change user passwords and potentially take over administrator accounts. Note: This can only be exploited unauthenticated if the attacker knows which page contains the 'truelysell_edit_staff' shortcode.
