Sources and claim methodology

Upstream source description

Missing authentication has been found in remote-execution task updates in the smart_proxy_dynflow package. The progress and completion callbacks accept a report when the one-time token is missing. A network attacker or user must already know the identifier of a running job. This applies when remote execution is set to pull or pull-mqtt mode. They can send their own job output and mark the job as a success or a failure. The job is then recorded with that result.
