DescriptionHarness through 3.3.0 omits access control validation in the infrastructure provider read endpoint, allowing authenticated users to retrieve provider configurations from spaces they do not belong to. Attackers can query the GET /api/v1/infraproviders endpoint with arbitrary space identifiers to expose sensitive provider metadata including Docker endpoints, TLS certificate paths, and cloud project identifiers.
