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.","published":"2026-08-18T16:18:23.363","modified":"2026-08-18T16:18:23.363","cvss":{"score":9.3,"severity":"CRITICAL","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:N/I:H/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[],"fix":{"url":"https://github.com/Hmbown/CodeWhale/commit/9a34b5034d29f05d1f28fa61b04719ca6a741020","label":"Hmbown/CodeWhale@9a34b50"},"references":[{"type":"WEB","url":"https://github.com/Hmbown/CodeWhale/commit/9a34b5034d29f05d1f28fa61b04719ca6a741020"},{"type":"WEB","url":"https://github.com/Hmbown/CodeWhale/security/advisories/GHSA-7j5w-7r7x-9v27"},{"type":"WEB","url":"https://www.vulncheck.com/advisories/codewhale-before-argument-injection-via-git-show"}],"provenance":{"sources":["OSV.dev","NVD","FIRST.org (EPSS)"],"lastVerified":"2026-08-18T16:18:23.363"}}
