{"apiVersion":"1.0","identifier":"CVE-2026-75913","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.","publishedAt":"2026-08-18T16:18:23","lastModifiedAt":"2026-08-18T16:18:23","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-75913","cvssScore":9.3,"cvssVector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:N/I:H/A:H","epssProbability":0.0033,"riskScore":0.96,"affectedProduct":"codewhale","affectedVersions":">=0.8.41,<0.8.64","vulnerabilityType":"Library","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-75913","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-75913","en":"https://www.redsauce.net/en/cves/CVE-2026-75913","fr":"https://www.redsauce.net/fr/cves/CVE-2026-75913","pt":"https://www.redsauce.net/pt/cves/CVE-2026-75913","de":"https://www.redsauce.net/de/cves/CVE-2026-75913","sk":"https://www.redsauce.net/sk/cves/CVE-2026-75913","el":"https://www.redsauce.net/el/cves/CVE-2026-75913"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-75913"}}
