Title
CodeWhale before 0.8.64 Argument Injection via git_show
Summary
CodeWhale (codewhale / codewhale-tui) versions >= 0.8.41 and < 0.8.64 contain an argument injection vulnerability in the git_show tool. The model-supplied rev parameter is passed unvalidated into the git show argv without an --end-of-options sentinel, so a value beginning with --output= is interpreted as a git flag. Because the tool is registered as auto-approved and advertised as read-only, an attacker (via a malicious repository combined with prompt injection) can cause an unprompted arbitrary file write at the privilege of the invoking user, targeting sensitive files such as ~/.ssh/authorized_keys, ~/.bashrc, or ~/.gitconfig. Fixed in 0.8.64 by adding rev validation.
