How to Fix CVE-2022-1929

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

devcert fixed: 1.2.1 
npm install devcert@1.2.1
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 devcert

How to Check if You Are Affected

To determine whether your Node.js application is affected by CVE-2022-1929, inspect your project dependencies using npm:

npm ls devcert

Analyze the terminal output to locate any version of Devcert in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 1.2.1), your application is affected.

Note: The npm ls devcert 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 Devcert, 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

An exponential ReDoS (Regular Expression Denial of Service) can be triggered in the devcert npm package, when an attacker is able to supply arbitrary input to the certificateFor method
