Overview
Affected versions of this package are vulnerable to Improper Check for Unusual or Exceptional Conditions in the HandleCreateSmPolicyRequest process when a downstream OpenAPI consumer call returns a 404 error and the response struct is nil. An attacker can cause the application to panic and return an HTTP 500 error by sending a crafted POST request that triggers a failed downstream lookup, such as providing an unknown dnn value. This is only exploitable if the endpoint is accessible without authentication due to missing inbound auth middleware.
