The expand() function exhibits exponential-time complexity in the number of consecutive non-expanding '{}' brace groups. An attacker who passes a crafted string to expand(), directly or transitively, can cause significant CPU consumption and event-loop blocking. The max option does not mitigate this, as it bounds the output size rather than the recursion work.","state":0,"publishedAt":"2026-06-30T10:16:34.56+00:00","modifiedAt":"2026-10-25T21:10:00.77+00:00","affected":[],"metrics":[{"system":"CVSS 4.0 · 22e2d327-25fe-45d7-9f0c-dcd23b7108df · Secondary","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:P/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:N/AU:Y/R:U/V:D/RE:M/U:Amber","score":7.7,"severity":"HIGH"}],"references":["https://github.com/juliangruber/brace-expansion/commit/c7e33ec13ac1a684c116720843ce24e208611754","https://www.npmjs.com/package/brace-expansion"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-13149","license":"NIST NVD usage terms; underlying source attribution retained","enrichment":{"sourceStatus":"Deferred","weaknesses":["CWE-400","CWE-407"],"productCriteria":[],"sourceDates":{"published":"2026-06-30T10:16:34.560","lastModified":"2026-10-25T21:10:00.770"},"relatedAdvisories":[],"note":"NVD analysis and CPE criteria are source context, not proof that a package or your environment is affected.
