CVE-2026-75913
CriticalCVSS 9.3Summary
CodeWhale (codewhale / codewhale-tui) versions >= 0.8.41 and < 0.8.64 contain an argument injection vulnerability in the git_show tool. The rev parameter is passed unvalidated to git show, allowing arbitrary file writes.
Risk Assessment
The vulnerability allows an attacker to write to sensitive user files such as ~/.ssh/authorized_keys, potentially leading to system compromise.
Recommendation
It is recommended to update CodeWhale to version 0.8.64 or later and avoid using the tool with untrusted repositories.
Original NVD description (English source)
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.
