The attack vector is remote over HTTP GET to the vulnerable parameters and does not require prior authentication; a crafted request suffices. Successful exploitation would likely lead to a device crash or service disruption rather than confirmed code execution."}}}}, "created": "2026-04-09T08:22:43.428740+00:00", "updated": "2026-04-13T14:26:02.113743+00:00", "vendors": ["d-link", "d-link$PRODUCT$di-8003"]}
