How to Fix CVE-2022-0639

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

url-parse fixed: 1.5.7 
npm install url-parse@1.5.7
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 url-parse

How to Check if You Are Affected

To determine whether your Node.js application is affected by CVE-2022-0639, inspect your project dependencies using npm:

npm ls url-parse

Analyze the terminal output to locate any version of Url parse in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 1.5.7), your application is affected.

Note: The npm ls url-parse 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-639: Authorization Bypass Through User-Controlled Key, where the system's authorization functionality does not prevent one user from gaining access to another user's data or record by modifying the key value identifying the data. In Url parse, 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

A specially crafted URL with an '@' sign but empty user info and no hostname, when parsed with url-parse, url-parse will return the incorrect href. In particular, ```js parse(\"http://@/127.0.0.1\") ``` Will return: ```yaml { slashes: true, protocol: 'http:', hash: '', query: '', pathname: '/127.0.0.1', auth: '', host: '', port: '', hostname: '', password: '', username: '', origin: 'null', href: 'http:///127.0.0.1' } ``` If the 'hostname' or 'origin' attributes of the output from url-parse are used in security decisions and the final 'href' attribute of the output is then used to make a request, the decision may be incorrect.
