How to Fix CVE-2022-37259

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

steal fixed: Latest secure release 
npm install steal@Latest secure release
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 steal

How to Check if You Are Affected

To determine whether your Node.js application is affected by CVE-2022-37259, inspect your project dependencies using npm:

npm ls steal

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

Note: The npm ls steal 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-1333: Inefficient Regular Expression Complexity, where the product uses a regular expression with a worst-case computational complexity that is inefficient and possibly exponential. In Steal, 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 Regular Expression Denial of Service (ReDoS) flaw was found in stealjs steal 2.2.4 via the string variable in babel.js.
