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":"2026-06-30T08:30:34.502+00:00","modifiedAt":"2026-07-08T11:38:35.974+00:00","affected":[{"ecosystem":"https://registry.npmjs.org","name":"brace-expansion","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"juliangruber\",\n                    \"product\": \"brace-expansion\",\n                    \"collectionURL\": \"https://registry.npmjs.org\",\n                    \"packageName\": \"brace-expansion\",\n                    \"repo\": \"https://github.com/juliangruber/brace-expansion\",\n                    \"versions\": [\n                        {\n                            \"status\": \"affected\",\n                            \"version\": \"0\",\n                            \"lessThanOrEqual\": \"5.0.6\",\n                            \"versionType\": \"semver\"\n                        }\n                    ],\n                    \"defaultStatus\": \"unaffected\"\n                }"}],"metrics":[{"system":"CVSS 4.0","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/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://www.cve.org/CVERecord?id=CVE-2026-13149","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-13149","identifiers":["CVE-2026-13149"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
