How to Fix CVE-2021-41167

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

modern-async fixed: 1.0.4 
npm install modern-async@1.0.4
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 modern-async

How to Check if You Are Affected

To determine whether your Node.js application is affected by CVE-2021-41167, inspect your project dependencies using npm:

npm ls modern-async

Analyze the terminal output to locate any version of Modern async in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 1.0.4), your application is affected.

Note: The npm ls modern-async 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 Modern async, 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 This is a bug affecting two of the functions in this library: `forEachSeries` and `forEachLimit`. They should limit the concurrency of some actions but, in practice, they don't. Any code calling these functions will be written thinking they would limit the concurrency but they won't. This could lead to potential security issues in other projects. ### Patches The problem has been patched in 1.0.4. ### Workarounds There is no workaround aside from upgrading to 1.0.4.
