Vulnerability Overview

The REST API TO MiniProgram plugin for WordPress is vulnerable to privilege escalation via account takeovr in all versions up to, and including, 4.7.1 via the updateUserInfo() due to missing validation on the 'openid' user controlled key that determines what user will be updated. This makes it possible for unauthenticated attackers to update arbitrary user's accounts, including their email to a @weixin.com email, which can the be leveraged to reset the password of the user's account, including administrators.

Technical Analysis

REMEDIATION: Update to version 4.7.6, 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.
