A server-side request forgery (SSRF) issue exists in the APICall feature. The `URL` field within a Policy's ServiceCall configuration lacks validation, allowing a user with namespace-level Policy creation permissions to force the system to make HTTP requests to arbitrary internal resources, such as cloud metadata endpoints or resources belonging to other tenants. This is a Confused Deputy problem, where the system uses its high-privilege cluster-wide ServiceAccount to execute requests. Consequently, sensitive data, including cloud IAM credentials and secrets from other tenants, may be returned in the PolicyReport and accessed by the attacker, compromising multi-tenant isolation.
