Hi,

The following vulnerability was published for node-minimatch.

CVE-2026-26996[0]:
| 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.
