Password disclosure via unmasked authentication error request
Published Apr 9, 2020 · Updated Aug 4, 2024
Credential exposure in Auth0 Auth0.js 8.0.0 through 9.13.1 allows attackers to read plaintext passwords from unfiltered error objects. The wrapCallback response handler retains the complete original error, including original.response.req._data.password, instead of masking that field. Exposure requires an integrating application to store or display the error object without filtering; the reported consequence is password disclosure.
