Technical details

This is a server-side request forgery (SSRF) vulnerability (CWE-918) in CloudVision Portal's OIDC bearer token validation logic. The flaw requires an authenticated user with high privileges to configure OIDC and enable bearer token login in cluster management settings. An attacker can then craft requests that traverse internal networks or access restricted resources by exploiting insufficient validation of bearer token configuration.
