Vulnerable Library - body-parser-1.20.3.tgz

Dependency Hierarchy:

  • express-4.21.2.tgz
    • ❌ body-parser-1.20.3.tgz (Vulnerable Library)

Found in base branch: main

Vulnerability Details

body-parser 2.2.0 is vulnerable to denial of service due to inefficient handling of URL-encoded bodies with very large numbers of parameters. An attacker can send payloads containing thousands of parameters within the default 100KB request size limit, causing elevated CPU and memory usage. This can lead to service slowdown or partial outages under sustained malicious traffic.
This issue is addressed in version 2.2.1.

    • ❌ micromatch-4.0.2.tgz (Vulnerable Library)

Found in base branch: main

Vulnerability Details

The NPM package "micromatch" prior to 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 persists. This issue should be mitigated by using a safe pattern that won't start backtracking the regular expression due to greedy matching. This issue was fixed in version 4.0.8. After conducting a further research, it was concluded that CVE-2024-4067 should not reflect the security risk score in NVD, but will be kept for users' awareness.

CVE-2025-7339

Vulnerable Library - on-headers-1.0.2.tgz

Execute a listener when a response is about to write headers

Library home page: https://registry.npmjs.org/on-headers/-/on-headers-1.0.2.tgz

Path to dependency file: /package.json

Path to vulnerable library: /package.json

Dependency Hierarchy:

• webpack-dev-server-5.2.2.tgz (Root Library)
  • compression-1.7.4.tgz
    • ❌ on-headers-1.0.2.tgz (Vulnerable Library)

Found in base branch: main

Vulnerability Details

on-headers is a node.js middleware for listening to when a response writes headers. A bug in on-headers versions "<1.1.0" may result in response headers being inadvertently modified when an array is passed to "response.writeHead()". Users should upgrade to version 1.1.0 to receive a patch. Uses are strongly encouraged to upgrade to "1.1.0", but this issue can be worked around by passing an object to "response.writeHead()" rather than an array.
Mend Note: The description of this vulnerability differs from MITRE.
