  • Rule ID: javascript_lang_exception

Leaking sensitive data to an exception is a common cause of data leaks and can lead to data breaches. This rule looks for instances of sensitive data sent to exceptions.


❌ Avoid using sensitive data in exception messages:

throw new CustomError(`Error with ${}`)

✅ If you need to identify a user, ensure to use their unique identifier instead of their personal identifiable information:

throw new CustomError(`Error with ${user.uuid}`)
