modern-async's `forEachSeries` and `forEachLimit` functions do not limit the number of requests
Publisher and source text is retained separately from QFinch interpretation.
QFinch assessment
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.

Matching a version is only one part of assessing exposure. QFinch has not assessed your environment on this public page.
Remediation
Apply the vendor-supported fixed release or mitigation, then verify the affected component is no longer reachable.
- Confirm the affected product and reachable code path exist in your environment.
- Apply the vendor-supported patch or mitigation from the primary advisory.
- Rescan the exact deployed revision and retain verification evidence.
