Prior to 1.29.4, the Claude Code Studio server launched by the --studio option in cli-tool/src/sandbox-server.js binds to all interfaces on port 3444, permits cross-origin requests, and requires no authentication. The POST /api/execute endpoint passes the prompt request-body field to executeLocalTask(), and POST /api/install-agent passes the agentName request-body field to a child process. The same unsafe agent field path is reachable from /api/execute through checkAndInstallAgent(). These attacker-controlled values reach child_process.spawn() with shell execution enabled, causing Node.js to construct a shell command in which metacharacters are interpreted. An attacker who can reach the port directly, or who convinces a developer running Studio to visit a malicious website, can execute arbitrary operating-system commands with the developer's privileges and compromise source code, credentials, and local data. This issue is fixed in version 1.29.4.","state":0,"publishedAt":"2026-08-11T18:27:09.297+00:00","modifiedAt":"2026-08-13T13:54:28.645+00:00","affected":[{"ecosystem":"Vendor product","name":"claude-code-templates","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"davila7\",\n                    \"product\": \"claude-code-templates\",\n                    \"versions\": [\n                        {\n                            \"version\": \"< 1.29.4\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","score":8.8,"severity":"HIGH"}],"references":["https://github.com/davila7/claude-code-templates/security/advisories/GHSA-79wm-x847-7cvg","https://github.com/davila7/claude-code-templates/commit/bc4618b07232633c1c0aac12a43e436268d31783","https://github.com/davila7/claude-code-templates/blob/main/CHANGELOG.md"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-73222","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-73222","identifiers":["CVE-2026-73222"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
