DescriptionGitHub Advisory

minimatch is a minimal matching utility for converting glob expressions into JavaScript RegExp objects. Prior to version 10.2.3, 9.0.7, 8.0.6, 7.4.8, 6.2.2, 5.1.8, 4.2.5, and 3.1.4, nested *() extglobs produce regexps with nested unbounded quantifiers (e.g. (?:(?:a|b)*)*), which exhibit catastrophic backtracking in V8. With a 12-byte pattern *(*(*(a|b))) and an 18-byte non-matching input, minimatch() stalls for over 7 seconds. Adding a single nesting level or a few input characters pushes this to minutes. This is the most severe finding: it is triggered by the default minimatch() API with no special options, and the minimum viable pattern is only 12 bytes. The same issue affects +() extglobs equally. Versions 10.2.3, 9.0.7, 8.0.6, 7.4.8, 6.2.2, 5.1.8, 4.2.5, and 3.1.4 fix the issue.

AnalysisAI

Minimatch versions prior to 10.2.3 (and earlier affected versions) suffer from ReDoS vulnerabilities in nested extglob patterns that generate regexps with catastrophic backtracking, allowing remote attackers to cause denial of service with minimal input. A 12-byte glob pattern like *(*(*(a|b))) combined with an 18-byte non-matching string can hang the application for 7+ seconds, with larger patterns stalling for minutes. …
