Hi,

The following vulnerability was published for node-micromatch.

CVE-2024-4067[0]:
| The NPM package `micromatch` 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.
