{"id":"CVE-2026-112366","summary":"Picomatch through 4.0.7 ReDoS via single-branch repeated extglob patterns","details":"Picomatch through 4.0.7 contains a regular expression denial of service vulnerability that allows attackers to block the event loop by supplying single-branch repeated extglob patterns. 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.","modified":"2026-10-20T02:45:29.279479139Z","published":"2026-10-19T15:29:00.491Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/112xxx/CVE-2026-112366.json","cna_assigner":"VulnCheck","cwe_ids":["CWE-1333"]},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/112xxx/CVE-2026-112366.json"},{"type":"PACKAGE","url":"https://github.com/micromatch/picomatch"},{"type":"ARTICLE","url":"https://github.com/micromatch/picomatch/blob/4.0.7/lib/parse.js#L287-L307"},{"type":"FIX","url":"https://github.com/micromatch/picomatch/pull/194"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-112366"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/picomatch-through-4.0.7-redos-via-single-branch-repeated-extglob-patterns"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/micromatch/picomatch","events":[{"introduced":"0"},{"last_affected":"6bb40679c218cefba5d4e9662408c5fdf699a8bb"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"last_affected":"4.0.7"}],"source":"AFFECTED_FIELD"}}],"versions":["4.0.7","4.0.6","4.0.5","4.0.4","3.0.1","2.3.1","4.0.3","4.0.2","4.0.1","3.0.0","2.3.0","2.2.3","2.2.2","2.1.0","2.0.7","2.0.6","2.0.5","2.0.4","2.0.3","2.0.2","2.0.1","2.0.0","1.1.2","1.1.0","1.0.2","1.0.1"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-112366.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"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"}]}
