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.
