Attackers can provide globs like +(*) or +(*a), which analyzeRepeatedExtglob in lib/parse.js skips, causing exponential backtracking against short crafted strings and denying service to Node.js applications.","state":0,"publishedAt":"2026-10-19T15:29:00.491+00:00","modifiedAt":"2026-10-19T16:40:19.321+00:00","affected":[{"ecosystem":"Vendor product","name":"picomatch","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"micromatch\",\n                    \"product\": \"picomatch\",\n                    \"defaultStatus\": \"unaffected\",\n                    \"versions\": [\n                        {\n                            \"version\": \"0\",\n                            \"lessThanOrEqual\": \"4.0.7\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"semver\"\n                        }\n                    ],\n                    \"packageURL\": \"pkg:npm/picomatch\",\n                    \"repo\": \"https://github.com/micromatch/picomatch\"\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","score":8.7,"severity":"HIGH"},{"system":"CVSS 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,"severity":"HIGH"}],"references":["https://github.com/micromatch/picomatch/pull/194","https://github.com/micromatch/picomatch/blob/4.0.7/lib/parse.js#L287-L307","https://www.vulncheck.com/advisories/picomatch-through-4.0.7-redos-via-single-branch-repeated-extglob-patterns"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-112366","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-112366","identifiers":["CVE-2026-112366"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
