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.","state":0,"publishedAt":"2026-08-18T16:18:23.363+00:00","modifiedAt":"2026-10-22T22:10:00.25+00:00","affected":[],"metrics":[{"system":"CVSS 4.0 · disclosure@vulncheck.com · Secondary","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:P/VC:N/VI:H/VA:H/SC:N/SI:H/SA:H/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X","score":8.5,"severity":"HIGH"},{"system":"CVSS 3.1 · disclosure@vulncheck.com · Primary","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:N/I:H/A:H","score":9.3,"severity":"CRITICAL"}],"references":["https://github.com/Hmbown/CodeWhale/commit/9a34b5034d29f05d1f28fa61b04719ca6a741020","https://github.com/Hmbown/CodeWhale/security/advisories/GHSA-7j5w-7r7x-9v27","https://www.vulncheck.com/advisories/codewhale-before-argument-injection-via-git-show"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-75913","license":"NIST NVD usage terms; underlying source attribution retained","enrichment":{"sourceStatus":"Deferred","weaknesses":["CWE-73"],"productCriteria":[],"sourceDates":{"published":"2026-08-18T16:18:23.363","lastModified":"2026-10-22T22:10:00.250"},"relatedAdvisories":[],"note":"NVD analysis and CPE criteria are source context, not proof that a package or your environment is affected.
