{"cve":"CVE-2026-75913","nvd":{"published":"2026-08-18T16:18:23.363","modified":"2026-10-22T22:10:00.250","status":"Deferred","description":"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.","cvss_v4":{"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","score":8.5},"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:N/I:H/A:H","score":9.3},"cwes":["CWE-73"],"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"],"products":[],"source":"nvd","synced_at":"2026-10-23T16:39:26.291718493+00:00"},"epss":{"cve":"CVE-2026-75913","score":0.00477,"percentile":0.40919,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-7j5w-7r7x-9v27","url":"https://osv.dev/vulnerability/GHSA-7j5w-7r7x-9v27","summary":"CodeWhale: Argument Injection in `git_show` Tool Allows Arbitrary File Write Without Approval","modified":"2026-09-04T19:00:04.282032993Z","packages":[{"ecosystem":"crates.io","name":"deepseek-tui","purl":"pkg:cargo/deepseek-tui","ranges":[">=0.3.27 <=0.8.41"],"fixed":[]},{"ecosystem":"npm","name":"deepseek-tui","purl":"pkg:npm/deepseek-tui","ranges":[">=0.3.27 <0.8.41"],"fixed":["0.8.41"]},{"ecosystem":"crates.io","name":"codewhale-tui","purl":"pkg:cargo/codewhale-tui","ranges":[">=0.8.41 <0.8.64"],"fixed":["0.8.64"]},{"ecosystem":"npm","name":"codewhale","purl":"pkg:npm/codewhale","ranges":[">=0.8.41 <0.8.64"],"fixed":["0.8.64"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
