Vulnerability Overview

The WP User Profile Avatar plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 1.0.0 via the remove_user_avatar and update_user_avatar functions due to missing validation on a user controlled key. This makes it possible for unauthenticated attackers to update and delete arbitrary avatars.

Technical Analysis

REMEDIATION: Update to version 1.0.1, or a newer patched version --- IDENTIFIER: CWE-639 (Authorization Bypass Through User-Controlled Key) The system's authorization functionality does not prevent one user from gaining access to another user's data or record by modifying the key value identifying the data.
