CVE-2024-36588Network attack vector

Message impersonation via trusted sender parameter

Published Jun 13, 2024 · Updated Nov 21, 2024

Incorrect access control in Anonymous Locker LLC's Anonshop Backend commit 2b2b4 allows remote attackers to impersonate users via HTTP requests. The sendMessage.js serverless function accepts the request's sender parameter as the message author without verifying that the requester controls that identity. No authentication is required, but another user must interact with the forged message; the documented consequence is false attribution rather than data disclosure or service interruption.
