GitAhead vulnerabilities

GitAhead through version 2.7.1 on macOS contains a command injection vulnerability that allows attackers to execute shell commands by crafting repository filenames. Attackers can commit a file whose path contains a double quote and a payload, which runs when 'Show in Finder' is selected.

GitAhead through version 2.7.1 contains an OS command injection vulnerability in src/git/Filter.cpp that allows malicious repositories to execute commands by substituting crafted filenames into clean/smudge filter commands. Attackers can ship files named with $(command) selected via .gitattributes so checkout or staging runs the command through bash -c as the victim.

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. A network attacker presenting an invalid certificate once can intercept later automatic update checks, offer a fake version, and execute code as the user upon installation.
