{"id":"CVE-2026-26996","aliases":["GHSA-3ppc-4f35-3m26"],"url":"https://o3.security/vulnerability/CVE-2026-26996","summary":"minimatch has a ReDoS via repeated wildcards with non-matching literal in pattern","details":"minimatch is a minimal matching utility for converting glob expressions into JavaScript RegExp objects. Versions 10.2.0 and below are vulnerable to Regular Expression Denial of Service (ReDoS) when a glob pattern contains many consecutive * wildcards followed by a literal character that doesn't appear in the test string. Each * compiles to a separate [^/]*? regex group, and when the match fails, V8's regex engine backtracks exponentially across all possible splits. The time complexity is O(4^N) where N is the number of * characters. With N=15, a single minimatch() call takes ~2 seconds. With N=34, it hangs effectively forever. Any application that passes user-controlled strings to minimatch() as the pattern argument is vulnerable to DoS. This issue has been fixed in version 10.2.1.","published":"2026-02-20T03:05:21.105Z","modified":"2026-07-28T18:30:31.539370014Z","cvss":null,"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"npm","name":"minimatch","fixedVersion":"10.2.1"},{"ecosystem":"npm","name":"minimatch","fixedVersion":"9.0.6"},{"ecosystem":"npm","name":"minimatch","fixedVersion":"8.0.5"},{"ecosystem":"npm","name":"minimatch","fixedVersion":"7.4.7"},{"ecosystem":"npm","name":"minimatch","fixedVersion":"6.2.1"},{"ecosystem":"npm","name":"minimatch","fixedVersion":"5.1.7"},{"ecosystem":"npm","name":"minimatch","fixedVersion":"4.2.4"},{"ecosystem":"npm","name":"minimatch","fixedVersion":"3.1.3"}],"fix":{"url":"https://github.com/isaacs/minimatch/commit/2e111f3a79abc00fa73110195de2c0f2351904f5","label":"isaacs/minimatch@2e111f3"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/26xxx/CVE-2026-26996.json"},{"type":"ADVISORY","url":"https://github.com/isaacs/minimatch/security/advisories/GHSA-3ppc-4f35-3m26"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-26996"},{"type":"FIX","url":"https://github.com/isaacs/minimatch/commit/2e111f3a79abc00fa73110195de2c0f2351904f5"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-07-28T18:30:31.539370014Z"}}
