micromatch is vulnerable to Regular Expression Denial of Service (ReDoS). The vulnerability is due a regex expression with inefficient complexity within the micromatch.braces() method. An attacker can submit a large payload without a closing bracket, which results in Regular Expression Denial of Service (ReDoS) as the application slows down, hangs or crashes.
