CVE-2020-36923Public exploitNetwork attack vector

Unauthenticated management access via client-side route controls

Published Jan 6, 2026 · Updated Jan 6, 2026

Authorization bypass in Sony BRAVIA Digital Signage 1.7.8 and earlier allows remote attackers to access hidden management resources. The management web application relies on client-side route restrictions, so directly opening /#/content-creation bypasses the intended authorization check. No account or user interaction is required; published evidence demonstrates unauthorized interface access but does not establish data modification or service interruption.
