GitAhead 2.5.0 through 2.7.1 contains an insecure update mechanism that installs downloaded updates without integrity or signature verification and permanently ignores TLS errors after one SSL error dialog. Network attackers presenting an invalid certificate once can intercept later automatic update checks, offer a fake version, and execute code as the user upon installation.
