Simplr Registration Form Plus+ <= 2.4.5 - Subscriber+ Arbitrary User Password Change via IDOR

Description

The plugin is vulnerable to Insecure Direct Object References in versions up to, and including, 2.4.5. 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 authenticated attackers with subscriber-level permissions or above to change user passwords and potentially take over administrator accounts.
