KubeSphere through 4.1.3 contains a server-side request forgery vulnerability in the git credential verification endpoint that accepts unvalidated caller-supplied URLs without allowlist restrictions. Authenticated attackers can supply arbitrary URLs to reach internal services and exfiltrate basic-auth credentials from Secrets in any namespace by leveraging the endpoint's error response handling.
