{"id":"CVE-2026-26996","state":"PUBLISHED","title":"minimatch has a ReDoS via repeated wildcards with non-matching literal in pattern","description":"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.","publishedAt":"2026-02-20T03:05:21.105Z","updatedAt":"2026-02-20T15:34:15.151Z","severity":{"score":8.7,"label":"High","version":"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","source":"GitHub_M"},"assigner":"GitHub_M","products":["isaacs minimatch"],"affected":[{"vendor":"isaacs","product":"minimatch","versions":[{"version":"< 10.2.1","status":"affected"}]}],"references":["https://github.com/isaacs/minimatch/security/advisories/GHSA-3ppc-4f35-3m26","https://github.com/isaacs/minimatch/commit/2e111f3a79abc00fa73110195de2c0f2351904f5"],"weaknesses":["CWE-1333"],"ingestedAt":"2026-10-29T20:11:21.040Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/26xxx/CVE-2026-26996.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-26996","state":"PUBLISHED","datePublished":"2026-02-20T03:05:21.105Z","dateUpdated":"2026-02-20T15:34:15.151Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2026-02-17T01:41:24.607Z"},"containers":{"cna":{"title":"minimatch has a ReDoS via repeated wildcards with non-matching literal in pattern","descriptions":[{"lang":"en","value":"minimatch is a minimal matching utility for converting glob expressions into JavaScript RegExp objects.
