{"id":"CVE-2026-31861","summary":"Shell Command Injection in Git Routes [CloudCLI UI]","details":"Cloud CLI (aka Claude Code UI) is a desktop and mobile UI for Claude Code, Cursor CLI, Codex, and Gemini-CLI. Prior to 1.24.0, The /api/user/git-config endpoint constructs shell commands by interpolating user-supplied gitName and gitEmail values into command strings passed to child_process.exec(). The input is placed within double quotes and only \" is escaped, but backticks (`), $() command substitution, and \\ sequences are all interpreted within double-quoted strings in bash. This allows authenticated attackers to execute arbitrary OS commands via the git configuration endpoint. This vulnerability is fixed in 1.24.0.","aliases":["GHSA-7fv4-fmmc-86g2"],"modified":"2026-04-10T05:42:51.245757Z","published":"2026-03-11T17:22:10.111Z","database_specific":{"cwe_ids":["CWE-94"],"cna_assigner":"GitHub_M","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/31xxx/CVE-2026-31861.json"},"references":[{"type":"WEB","url":"https://github.com/siteboon/claudecodeui/releases/tag/v1.24.0"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/31xxx/CVE-2026-31861.json"},{"type":"ADVISORY","url":"https://github.com/siteboon/claudecodeui/security/advisories/GHSA-7fv4-fmmc-86g2"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-31861"},{"type":"FIX","url":"https://github.com/siteboon/claudecodeui/commit/86c33c1c0cb34176725a38f46960213714fc3e04"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/siteboon/claudecodeui","events":[{"introduced":"0"},{"fixed":"bc164140e031f8010a4e672ac8bc20b61e84701a"}]}],"versions":["V1.7.0","v1.1.0","v1.1.1","v1.1.2","v1.1.3","v1.1.4","v1.10.0","v1.10.1","v1.10.2","v1.10.3","v1.10.4","v1.10.5","v1.11.0","v1.12.0","v1.13.0","v1.13.2","v1.13.3","v1.13.5","v1.13.6","v1.14.0","v1.15.0","v1.16.2","v1.16.3","v1.16.4","v1.17.1","v1.18.0","v1.18.1","v1.18.2","v1.19.0","v1.19.1","v1.2.0","v1.20.1","v1.21.0","v1.22.0","v1.22.1","v1.23.2","v1.5.0","v1.6.0","v1.6.1","v1.8.0","v1.8.1","v1.8.10","v1.8.12","v1.8.2","v1.8.3","v1.8.4","v1.8.5","v1.8.6","v1.8.8","v1.8.9","v1.9.0","v1.9.1"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-31861.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N"}]}
