Summary

The vulnerability in zxcvbn-ts, a password strength estimator, affects users on the nodeJS platform using the second argument of the zxcvbn function. It can lead to unbounded resource consumption as the user input array is extended with every function call.

Risk Assessment

Organizations may experience performance issues, and node processes can be killed due to excessive resource consumption. Browser users are less affected but may also encounter problems with a high number of input changes.

Recommendation

It is recommended to upgrade to version 3.0.2, where the issue has been patched. Users unable to upgrade should stop using the second argument of the zxcvbn function and use the zxcvbnOptions.setOptions function.

Original NVD description (English source)

zxcvbn-ts is an open source password strength estimator written in typescript. This vulnerability affects users running on the nodeJS platform which are using the second argument of the zxcvbn function. It can result in an unbounded resource consumption as the user inputs array is extended with every function call. Browsers are impacted, too but a single user need to do a lot of input changes so that it affects the browser, while the node process gets the inputs of every user of a platform and can be killed that way. This problem has been patched in version 3.0.2. Users are advised to upgrade. Users unable to upgrade should stop using the second argument of the zxcvbn function and use the zxcvbnOptions.setOptions function.
