GitAhead Update Mechanism Code Execution Vulnerability

Executive Summary

GitAhead 2.5.0 through 2.7.1 has an insecure auto-update mechanism that installs updates without verifying their integrity or authenticity. It also permanently ignores TLS errors after one SSL error dialog, allowing network attackers to intercept update checks, provide fake versions, and execute arbitrary code on the user's system.
