Summary
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.

"value": "minimatch es una utilidad de coincidencia m\u00ednima para convertir expresiones glob en objetos RegExp de JavaScript. Las versiones 10.2.0 e inferiores son vulnerables a la denegaci\u00f3n de servicio por expresi\u00f3n regular (ReDoS) cuando un patr\u00f3n glob contiene muchos comodines * consecutivos seguidos de un car\u00e1cter literal que no aparece en la cadena de prueba. Cada * se compila en un grupo de regex [^/]*? separado, y cuando la coincidencia falla, el motor de regex de V8 retrocede exponencialmente a trav\u00e9s de todas las posibles divisiones. La complejidad temporal es O(4^N) donde N es el n\u00famero de caracteres *. Con N=15, una sola llamada a minimatch() tarda ~2 segundos. Con N=34, se cuelga efectivamente para siempre. Cualquier aplicaci\u00f3n que pase cadenas controladas por el usuario a minimatch() como argumento de patr\u00f3n es vulnerable a DoS. Este problema ha sido solucionado en la versi\u00f3n 10.2.1."
