## Affected

- stiofansisland UsersWP – Front-end login form, User Registration, User Profile & Members Directory plugin for WP: through 1.2.63

## Description

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.
