How to Fix CVE-2022-31150

To remediate this vulnerability, upgrade all affected Undici dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

undici fixed: 5.8.0 
npm install undici@5.8.0
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

npm ls undici

How to Check if You Are Affected

To determine whether your Node.js application is affected by CVE-2022-31150, inspect your project dependencies using npm:

npm ls undici

Analyze the terminal output to locate any version of Undici in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 5.8.0), your application is affected.

Note: The npm ls undici command inspects dependencies declared in your package.json and lockfile; it does not perform automated runtime dynamic scanning.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-93: Improper Neutralization of CRLF Sequences ('CRLF Injection'), where the product uses crlf (carriage return line feeds) as a special element, e.g. to separate lines or records, but it does not neutralize or incorrectly neutralizes crlf sequences from inputs. In Undici, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

### Impact It is possible to inject CRLF sequences into request headers in Undici. ```js const undici = require('undici') const response = undici.request("http://127.0.0.1:1000", { headers: {'a': "\r\nb"} }) ``` The same applies to `path` and `method` ### Patches Update to v5.8.0 ### Workarounds Sanitize all HTTP headers from untrusted sources to eliminate `\r\n`. ### References https://hackerone.com/reports/409943 https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2018-12116 ### For more information If you have any questions or comments about this advisory: * Open an issue in [undici repository](https://github.com/nodejs/undici/issues) * To make a report, follow the [SECURITY](https://github.com/nodejs/node/blob/HEAD/SECURITY.md) document
