Executive Summary

Mattermost Desktop App versions prior to 6.0.0 do not enable the Hardened Runtime when packaged for the Mac App Store. This allows an attacker to copy the app binary to a temporary folder and inherit TCC (Transparency, Consent, and Control) permissions, potentially bypassing security restrictions.

Impact Analysis

This vulnerability can allow an attacker with limited privileges to gain access to permissions normally granted to the Mattermost Desktop App, potentially leading to unauthorized access to protected resources or data on a Mac system.
