UsersWP <= 1.2.63 - Insecure Direct Object Reference to Authenticated (Editor+) Arbitrary User Avatar/Banner Reset via 'user_id' Parameter

Summary

The UsersWP – Front-end login form, User Registration, User Profile & Members Directory plugin for WP plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 1.2.63 via the 'user_id' parameter due to missing validation on a user controlled key. This makes it possible for authenticated attackers, with editor-level access and above, to reset and permanently delete the avatar or banner image of any arbitrary user, including administrators, by clearing their avatar_thumb or banner_thumb metadata in the uwp_usermeta table.
