    Regular Expression Denial of Service (ReDoS) in micromatch

    CVE-2024-4067 · GHSA-952p-6rrq-rcjv

    Affected
    • npm micromatch < 4.0.8
    Fixed in
    4.0.8· Vendor fix available
    Issue
    The NPM package micromatch prior to version 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 persisted prior to https://github.com/micromatch/micromatch/pull/266. This issue should be mitigated by using a safe pattern that won't start backtracking the regular expression due to greedy matching.

    Recommended action: Upgrade to 4.0.8 or later, then redeploy and verify.A vendor fix does not resolve your finding until you verify it in your own systems.
