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.","published":"2026-10-19T16:17:07.500","modified":"2026-10-19T16:17:07.500","cvss":{"score":7.5,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[],"fix":{"url":"https://github.com/micromatch/picomatch/pull/194","label":"micromatch/picomatch#194"},"references":[{"type":"WEB","url":"https://github.com/micromatch/picomatch/blob/4.0.7/lib/parse.js#L287-L307"},{"type":"WEB","url":"https://github.com/micromatch/picomatch/pull/194"},{"type":"WEB","url":"https://www.vulncheck.com/advisories/picomatch-through-4.0.7-redos-via-single-branch-repeated-extglob-patterns"}],"provenance":{"sources":["OSV.dev","NVD","FIRST.org (EPSS)"],"lastVerified":"2026-10-19T16:17:07.500"}}
