Package

npm modern-async (npm)

Affected versions

< 1.0.4

Patched versions

1.0.4

Description

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.
