How to Fix CVE-2019-17592

To remediate this vulnerability, upgrade all affected Csv 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.

csv-parse fixed: 4.4.6 
npm install csv-parse@4.4.6
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 csv-parse

How to Check if You Are Affected

To determine whether your Node.js application is affected by CVE-2019-17592, inspect your project dependencies using npm:

npm ls csv-parse

Analyze the terminal output to locate any version of Csv parse in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 4.4.6), your application is affected.

Note: The npm ls csv-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-400: Uncontrolled Resource Consumption, where the product does not properly control the allocation and maintenance of a limited resource. In Csv 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

Versions of `csv-parse` prior to 4.4.6 are vulnerable to Regular Expression Denial of Service. The `__isInt()` function contains a malformed regular expression that processes large specially-crafted input very slowly, leading to a Denial of Service. This is triggered when using the `cast` option. ## Recommendation Upgrade to version 4.4.6 or later.
