CVE-2026-27904 is a regular-expression denial-of-service vulnerability in minimatch, a JavaScript glob-matching library that converts glob expressions into RegExp objects. In vulnerable releases prior to 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 extglob constructs using *() and similarly +() are compiled into regular expressions containing nested unbounded quantifiers. This can produce expressions equivalent to patterns such as nested repeated alternations, which trigger catastrophic backtracking in V8 when evaluated against non-matching input. The issue is reachable through the default minimatch() API without requiring special options, and even very short attacker-controlled patterns and inputs are sufficient to induce severe processing delays.
