VUL-0: CVE-2024-4067: python-panel: the npm package `micromatch` is vulnerable to Regular Expression Denial of Service (ReDoS)
Last modified: 2024-05-21 08:34:18 UTC
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.

Vulnerable versions of the micromatch package are embedded in: - openSUSE:Factory/python-panel micromatch (4.0.5) Upstream issue: https://github.com/micromatch/micromatch/issues/243
Same issue https://bugzilla.suse.com/show_bug.cgi?id=1224361, different CVE number. Probably not a real high score issue: https://github.com/micromatch/micromatch/issues/254 After an initial analysis of javascript code in this package the dependency graph is: braces <- micromatch <- fast-glob <- globby <- typescript-eslint/estree <- typescript-eslint/parser <- typescript-eslint This code is not part of this python package, it's a devel node module used upstream for developers, so we can certainly say that it's not affected by this bug.
Looks like there's a fix in braces upstream [1] to avoid this issue. There will be a new release soon. [1] https://github.com/micromatch/braces/pull/37
