{"affected":[{"product":"zuke","source":"CNA: GitHub_M","vendor":"zuke-build","versions":[{"status":"affected","version":"< 1.51.0"}]}],"cveId":"CVE-2026-119287","cwes":["CWE-862"],"description":"Zuke is a code-first, strongly typed build automation system for Deno. Prior to 1.51.0, the @zuke/core MCP registry mode accepts command-form registry descriptors without applying the ZUKE_REGISTRY_LAUNCH_HOSTS authorization enforced for remote module descriptors. When zuke mcp --registry --allow-run reads a registry writable by another party and a run-capable caller invokes the affected tool, the registry writer can choose the program and arguments executed with the operator's environment and workspace access. The --allow-run and --protect name globs do not contain the issue because the descriptor supplies those names, and the optional destructive confirmation displays a description controlled by the same writer. The local default registry populated only through zuke register is not affected because that command writes module-form descriptors. This issue is fixed in version 1.51.0.","epss":{"date":"2026-11-04","percentile":0.12998,"score":0.00223},"exploits":[],"kev":null,"metrics":[{"score":8,"severity":"high","source":"CNA: GitHub_M","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:U/C:H/I:H/A:H","version":"3.1"},{"score":8,"severity":"high","source":"NVD: security-advisories@github.com","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:U/C:H/I:H/A:H","version":"3.1"}],"modifiedAt":1793834238940,"publishedAt":1793374792468,"references":[{"source":"CNA: GitHub_M","tags":["x_refsource_CONFIRM"],"url":"https://github.com/zuke-build/zuke/security/advisories/GHSA-2rmh-5cw4-33gr"},{"source":"CNA: GitHub_M","tags":["x_refsource_MISC"],"url":"https://github.com/zuke-build/zuke/pull/542"},{"source":"CNA: GitHub_M","tags":["x_refsource_MISC"],"url":"https://github.com/zuke-build/zuke/commit/4257b0bc5ef5e387a44f913349646d4baccd1654"},{"source":"CNA: GitHub_M","tags":["x_refsource_MISC"],"url":"https://github.com/zuke-build/zuke/releases/tag/core-v1.51.0"},{"source":"security-advisories@github.com","tags":[],"url":"https://github.com/zuke-build/zuke/commit/4257b0bc5ef5e387a44f913349646d4baccd1654"},{"source":"security-advisories@github.com","tags":[],"url":"https://github.com/zuke-build/zuke/pull/542"},{"source":"security-advisories@github.com","tags":[],"url":"https://github.com/zuke-build/zuke/releases/tag/core-v1.51.0"},{"source":"security-advisories@github.com","tags":[],"url":"https://github.com/zuke-build/zuke/security/advisories/GHSA-2rmh-5cw4-33gr"}],"remediation":[],"revision":"1e7368d564689e0eca00efe631ea74c7788b41fbfb95c85a4b7434cd81d01f99","sources":[{"modifiedAt":1793833058406,"name":"CNA: GitHub_M","retrievedAt":1793833722068,"url":"https://www.cve.org/CVERecord?id=CVE-2026-119287"},{"modifiedAt":1793834238940,"name":"NVD","retrievedAt":1793838189846,"url":"https://nvd.nist.gov/vuln/detail/CVE-2026-119287"},{"modifiedAt":null,"name":"FIRST EPSS","retrievedAt":1793833727694,"url":"https://api.first.org/data/v1/epss?cve=CVE-2026-119287"}],"ssvc":{"assessedAt":1793833048343,"automatable":"no","exploitation":"none","source":"ADP: CISA-ADP","technicalImpact":"total"},"status":"published","title":"Zuke: Command-form registry descriptors bypass the MCP launch policy","updatedAt":1793838189846}
