The User Profile Picture plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 2.6.1 via the 'rest_api_change_profile_image' function due to missing validation on a user controlled key.

If an administrator approves or publishes a post or page with the shortcode to the imported form, any user can register as an administrator.

The ProfilePress plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the ProfilePress User Panel widget in all versions up to, and including, 4.15.8 due to insufficient input sanitization and output escaping on user supplied attributes.

The ARMember – Membership Plugin, Content Restriction, Member Levels, User Profile & User signup plugin for WordPress is vulnerable to Open Redirect in all versions up to, and including, 4.0.30.

This subsequently allows the attacker to register an account as an administrator on the site.
