Detailed vulnerability description
The vulnerability allows a remote user to perform unauthorized registration approval actions, including taking over an existing account.
The vulnerability exists due to cross-site request forgery in modules/registration.php when handling GET-based registration approval requests. A remote privileged user can trick a user with the rol_approve_users right into visiting a crafted URL to perform unauthorized registration approval actions, including taking over an existing account.
User interaction is required, and exploitation requires the attacker to have a pending registration so their user UUID is known from the registration confirmation email.
