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":"2026-08-11T19:18:51.72+00:00","modifiedAt":"2026-10-24T15:10:00.19+00:00","affected":[],"metrics":[{"system":"CVSS 3.1 · security-advisories@github.com · Secondary","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/blob/main/CHANGELOG.md","https://github.com/davila7/claude-code-templates/commit/bc4618b07232633c1c0aac12a43e436268d31783","https://github.com/davila7/claude-code-templates/security/advisories/GHSA-79wm-x847-7cvg"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-73222","license":"NIST NVD usage terms; underlying source attribution retained","enrichment":{"sourceStatus":"Awaiting Analysis","weaknesses":["CWE-78","CWE-306","CWE-352"],"productCriteria":[],"sourceDates":{"published":"2026-08-11T19:18:51.720","lastModified":"2026-10-24T15:10:00.190"},"relatedAdvisories":[],"note":"NVD analysis and CPE criteria are source context, not proof that a package or your environment is affected.
