Comment (by viva.mundo):

 Hi! Got this as feedback from a PEN test from a customer:

 A vulnerability in this package:

 https://security.snyk.io/package/npm/zxcvbn/4.4.1

 zxcvbn is a realistic password strength estimation

 Affected versions of this package are vulnerable to Regular Expression
 Denial of Service (ReDoS) via the repeat_match functionality, due to the
 usage of an insecure regex in lazy_anchored variable.

 There seems to be a fixed package at https://github.com/zxcvbn-ts/zxcvbn

 With migration guide at https://zxcvbn-
 ts.github.io/zxcvbn/guide/migration/
