Attackers can send a continuous loop of unauthenticated commands to override the physical remote, change volume and mute, and reset all picture and audio calibration settings.","epss":null,"exploits":[{"kind":"exploit","source":"CNA: VulnCheck","url":"https://github.com/yehia-mamdouh/Hisense-Smart-TV-Security-Research"}],"kev":null,"metrics":[{"score":4.8,"severity":"medium","source":"CNA: VulnCheck","vector":"CVSS:4.0/AV:A/AC:L/AT:N/PR:N/UI:A/VC:N/VI:L/VA:L/SC:N/SI:N/SA:N","version":"4.0"},{"score":4.6,"severity":"medium","source":"CNA: VulnCheck","vector":"CVSS:3.1/AV:A/AC:L/PR:N/UI:R/S:U/C:N/I:L/A:L","version":"3.1"}],"modifiedAt":1793991491841,"publishedAt":1793991491841,"references":[{"source":"CNA: VulnCheck","tags":["technical-description","exploit"],"url":"https://github.com/yehia-mamdouh/Hisense-Smart-TV-Security-Research"},{"source":"CNA: VulnCheck","tags":["third-party-advisory"],"url":"https://www.vulncheck.com/advisories/hisense-vidaa-smart-tv-upnp-dlna-missing-authentication"}],"remediation":[],"revision":"4bf9f2ce0a250194b4ce60233d62f26c9dcd4032106c11041393ce197c34009e","sources":[{"modifiedAt":1793991491841,"name":"CNA: VulnCheck","retrievedAt":1793992249708,"url":"https://www.cve.org/CVERecord?id=CVE-2026-123996"}],"ssvc":null,"status":"published","title":"Hisense VIDAA Smart TV UPnP/DLNA Missing Authentication","updatedAt":1793992249708}
