Vulnerability Title
Unauthenticated Localhost Admin Panel in Auth0 AD/LDAP Connector
Source: CVE Program / CVE List V5
Vulnerability Description
The administrative panel of the Auth0 AD/LDAP Connector (versions 6.5.0 and earlier) listens on the local loopback interface without requiring authentication. This allows a local, low-privileged user or process on the host system to access the panel's management endpoints without credentials. Through these endpoints, a local user can read configuration details, including plaintext Active Directory service account credentials, and modify connector settings.
