Prior to 1.1.20, 2.1.6, 3.0.8, and 5.0.11, deeply nested brace groups cause expand_() to recurse once per nesting level at comma-member and single-set expansion sites, exhausting the native stack before output limits can apply and potentially terminating the Node.js process. expand_ performs uncontrolled recursion for nested brace alternatives and single-part sets. deeply nested brace groups supplied as an untrusted pattern. expand_ is affected. expand is affected. Comma members is affected. Single set is affected. native stack exhaustion during nested sub-expansion. process-terminating denial of service. This issue is fixed in versions 1.1.20, 2.1.6, 3.0.8, and 5.0.11.","state":0,"publishedAt":"2026-09-28T21:17:16.517+00:00","modifiedAt":"2026-10-01T15:17:25.593+00:00","affected":[],"metrics":[{"system":"CVSS 3.1 · security-advisories@github.com · Secondary","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","score":7.5,"severity":"HIGH"}],"references":["https://github.com/juliangruber/brace-expansion/commit/1efee7c397c191da6287a78ec19512476a966a7b","https://github.com/juliangruber/brace-expansion/commit/935d78f32f335b2ff76578e5c5e877d31ae9888c","https://github.com/juliangruber/brace-expansion/commit/de84f144e9816f30e25fc8179e2e1249ab6df0db","https://github.com/juliangruber/brace-expansion/security/advisories/GHSA-qhr7-859c-m2p7"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-102278","license":"NIST NVD usage terms; underlying source attribution retained","enrichment":{"sourceStatus":"Deferred","weaknesses":["CWE-400","CWE-674"],"productCriteria":[],"sourceDates":{"published":"2026-09-28T21:17:16.517","lastModified":"2026-10-01T15:17:25.593"},"relatedAdvisories":[],"note":"NVD analysis and CPE criteria are source context, not proof that a package or your environment is affected.
