Summary
The NPM package `micromatch` prior to 4.0.8 is vulnerable to Regular Expression Denial of Service (ReDoS). The vulnerability occurs in `micromatch.braces()` in `index.js` because the pattern `.*` will greedily match anything. By passing a malicious payload, the pattern matching will keep backtracking to the input while it doesn't find the closing bracket. As the input size increases, the consumption time will also increase until it causes the application to hang or slow down. There was a merged fix but further testing shows the issue persists. This issue should be mitigated by using a safe pattern that won't start backtracking the regular expression due to greedy matching. This issue was fixed in version 4.0.8.

A medida que aumenta el tama\u00f1o de la entrada, el tiempo de consumo tambi\u00e9n aumentar\u00e1 hasta provocar que la aplicaci\u00f3n se cuelgue o se ralentice. Hubo una soluci\u00f3n combinada, pero pruebas adicionales muestran que el problema persiste. Este problema se debe mitigar mediante el uso de un patr\u00f3n seguro que no comience a retroceder la expresi\u00f3n regular debido a coincidencias codiciosas."
