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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","score":7.5},"cwes":["CWE-400","CWE-674"],"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"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:56:48.555445741+00:00"},"epss":{"cve":"CVE-2026-102278","score":0.00455,"percentile":0.39239,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-qhr7-859c-m2p7","url":"https://osv.dev/vulnerability/GHSA-qhr7-859c-m2p7","summary":"brace-expansion: DoS via uncontrolled recursion on nested brace groups causing stack exhaustion","modified":"2026-09-30T00:00:04.402763332Z","packages":[{"ecosystem":"npm","name":"brace-expansion","purl":"pkg:npm/brace-expansion","ranges":[">=4.0.0 <5.0.11"],"fixed":["5.0.11"]},{"ecosystem":"npm","name":"brace-expansion","purl":"pkg:npm/brace-expansion","ranges":[">=3.0.0 <3.0.8"],"fixed":["3.0.8"]},{"ecosystem":"npm","name":"brace-expansion","purl":"pkg:npm/brace-expansion","ranges":[">=2.0.0 <2.1.6"],"fixed":["2.1.6"]},{"ecosystem":"npm","name":"brace-expansion","purl":"pkg:npm/brace-expansion","ranges":["<1.1.20"],"fixed":["1.1.20"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
