Auth0 : Security Vulnerabilities, CVEs, Published In 2019 CVSS score >= 7

Auth0 auth0.net before 6.5.4 has Incorrect Access Control because IdentityTokenValidator can be accidentally used to validate untrusted ID tokens.

Auth0 Passport-SharePoint before 0.4.0 does not validate the JWT signature of an Access Token before processing. This allows attackers to forge tokens and bypass authentication and authorization mechanisms.

Auth0 Auth0-WCF-Service-JWT before 1.0.4 leaks the expected JWT signature in an error message when it cannot successfully validate the JWT signature. If this error message is presented to an attacker, they can forge an arbitrary JWT token that will be accepted by the vulnerable application.
