Comment 4 Tomas Hoger 2021-09-27 18:08:36 UTC 
This issue was introduced in ansi-regex 3.0.0 via this commit:

https://github.com/chalk/ansi-regex/commit/69bebf6b8b1ac9b4d70a411109b88bb650972f65
Comment 11 Tomas Hoger 2021-10-13 20:10:27 UTC 
This issue also affects npm and nodejs-nodemon packages, which bundle affected versions of ansi-regex.  There are multiple copies of ansi-regex in each of those packages included as their dependencies.
Comment 12 Tomas Hoger 2021-10-13 20:12:33 UTC 
Upstream bug report for npm about affected ansi-regex versions bundled with npm:

https://github.com/npm/cli/issues/3785

The latest npm version at the time - 8.0.0 - is still affected.
Comment 13 Tomas Hoger 2021-10-13 20:20:36 UTC 
The nodejs package are also affected.  In addition to including npm with affected ansi-regex versions (see comments above), it also includes a copy of the problematic regular expression in its internal modules:

https://github.com/nodejs/node/blob/v14.18.1/lib/internal/util/inspect.js#L201-L208

This regular expression was fixed (using the fix from the ansi-regex module) in nodejs version 16.11.0:
