{"id":"DEBIAN-CVE-2026-26996","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.","modified":"2026-06-15T19:06:13.648171267Z","published":"2026-02-20T03:16:01.620Z","upstream":["CVE-2026-26996"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-26996"}],"affected":[{"package":{"name":"node-minimatch","ecosystem":"Debian:11","purl":"pkg:deb/debian/node-minimatch?arch=source&distro=bullseye"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["3.0.4+~3.0.3-1","3.0.4+~3.0.3-1+deb11u1","3.0.4+~3.0.3-1+deb11u2","3.0.4+~3.0.5-1","3.0.5+~3.0.5-1","3.1.1+~3.0.5-1","5.0.0+~3.0.5-1","5.0.0+~3.0.5-2","5.1.0+~3.0.5-1","5.1.1+~5.1.2-1","9.0.3-1","9.0.3-2","9.0.3-3","9.0.3-4","9.0.3-5","9.0.3-6","9.0.7-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-26996.json"}},{"package":{"name":"node-minimatch","ecosystem":"Debian:12","purl":"pkg:deb/debian/node-minimatch?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["5.1.1+~5.1.2-1","9.0.3-1","9.0.3-2","9.0.3-3","9.0.3-4","9.0.3-5","9.0.3-6","9.0.7-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-26996.json"}},{"package":{"name":"node-minimatch","ecosystem":"Debian:13","purl":"pkg:deb/debian/node-minimatch?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["9.0.3-6","9.0.7-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-26996.json"}},{"package":{"name":"node-minimatch","ecosystem":"Debian:14","purl":"pkg:deb/debian/node-minimatch?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"9.0.7-1"}]}],"versions":["9.0.3-6"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-26996.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"}]}
