Prior to versions 5.0.5, 3.0.2, 2.0.3, and 1.1.13, a brace pattern with a zero step value (e.g., `{1..2..0}`) causes the sequence generation loop to run indefinitely, making the process hang for seconds and allocate heaps of memory. Versions 5.0.5, 3.0.2, 2.0.3, and 1.1.13 fix the issue. As a workaround, sanitize strings passed to `expand()` to ensure a step value of `0` is not used.","state":0,"publishedAt":"2026-03-27T15:16:57.297+00:00","modifiedAt":"2026-06-17T10:38:02.143+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:N/I:N/A:H","score":6.5,"severity":"MEDIUM"},{"system":"CVSS 3.1 · nvd@nist.gov · Primary","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/blob/daa71bcb4a30a2df9bcb7f7b8daaf2ab30e5794a/src/index.ts#L107-L113","https://github.com/juliangruber/brace-expansion/blob/daa71bcb4a30a2df9bcb7f7b8daaf2ab30e5794a/src/index.ts#L184","https://github.com/juliangruber/brace-expansion/commit/311ac0d54994158c0a384e286a7d6cbb17ee8ed5","https://github.com/juliangruber/brace-expansion/commit/7fd684f89fdde3549563d0a6522226a9189472a2","https://github.com/juliangruber/brace-expansion/commit/b9cacd9e55e7a1fa588fe4b7bb1159d52f1d902a","https://github.com/juliangruber/brace-expansion/issues/98","https://github.com/juliangruber/brace-expansion/pull/95","https://github.com/juliangruber/brace-expansion/pull/96","https://github.com/juliangruber/brace-expansion/pull/97","https://github.com/juliangruber/brace-expansion/security/advisories/GHSA-f886-m6hf-6m8v"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-33750","license":"NIST NVD usage terms; underlying source attribution retained","enrichment":{"sourceStatus":"Analyzed","weaknesses":["CWE-400"],"productCriteria":["cpe:2.3:a:juliangruber:brace-expansion:*:*:*:*:*:node.js:*:*"],"sourceDates":{"published":"2026-03-27T15:16:57.297","lastModified":"2026-06-17T10:38:02.143"},"relatedAdvisories":[],"note":"NVD analysis and CPE criteria are source context, not proof that a package or your environment is affected.
