The caller must already know the identifier of a running job. That identifier cannot be guessed, and this flaw does not reveal it. Privileges required are none (PR:N). The caller needs no account and no client certificate. The default mode is ssh, and in that mode the submitted result is discarded.\nThis flaw lets the caller write a job result. It does not let the caller read job data. The recorded job output, the recorded exit status, and the host's execution status in Satellite can be set by the caller, including to success.\n```\nThe vulnerable callback check was introduced in smart_proxy_dynflow version 0.4.0.
