The impact is confined to the victim\u2019s browser session, but if the interface has elevated privileges or integrated authentication it could have broader consequences. Exposure of the interface to the public Internet raises the risk; internal or firewall\u2011protected access reduces the likelihood."}}}}, "created": "2026-03-04T21:04:02.823941+00:00", "updated": "2026-04-16T13:45:21.955756+00:00", "vendors": ["international_datacasting_corporation_(idc)", "international_datacasting_corporation_(idc)$PRODUCT$sfx_series_superflex_satellite_receiver_web_management_interface"]}
