Descrição técnica

Hisense VIDAA Smart TV firmware V0000.01.00a.P0220 contains an unauthenticated access vulnerability where a QA build of the Google Cobalt browser engine exposes the WebDriver automation server on TCP port 4444 across all network interfaces without any authentication or pairing requirement. A LAN-adjacent attacker can connect to the exposed WebDriver service to execute arbitrary JavaScript, read and exfiltrate sensitive localStorage data including ACR telemetry, MAC addresses, ad-service credentials, and location data, inject persistent content onto the display, and access the window.hisense native bridge to perform filesystem read/write and system-state operations.

——0Tetragon is an eBPF-based security observability and runtime enforcement project. Versions before 1.7.0 can use a Helm default that exposes the privileged Tetragon gRPC API through an unauthenticated TCP listener on localhost:54321. An attacker who can run or compromise same-node hostNetwork pods can reach the listener and invoke privileged methods without authentication. These methods can add, delete, or reconfigure tracing policies and change debug settings, potentially resulting in privilege escalation or container escape. Version 1.7.0 changes the default endpoint to a Unix-domain socket. Deployments that do not expose an unauthenticated TCP listener are not affected.6h CVE-2026-1240277.5 ALT

——0ChatWiki before 2.10.0 contains a missing authentication vulnerability in the GET /manage/getLibRawFileOnePage route that allows unauthenticated attackers to read other tenants' documents. Attackers can enumerate sequential admin_user_id and file id query parameters, bypassing the ownership check, to retrieve PDF-rendered pages of any tenant's knowledge-base documents.6h CVE-2026-1239964.6 MÉD

——0Hisense VIDAA Smart TV firmware V0000.01.00a.P0220 contains a missing authentication vulnerability in the UPnP/DLNA RenderingControl service on TCP port 38400 that allows a LAN-adjacent attacker to issue SetVolume, SetMute, and SelectPreset(FactoryDefaults) commands after a one-time DLNA pairing with no per-command authentication or session token. 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.7h CVE-2026-1239954.6 MÉD

——0Hisense VIDAA Smart TV firmware V0000.01.00a.P0220 contains an input validation vulnerability in the UPnP/DLNA AVTransport SOAP service that allows a LAN-adjacent attacker to inject arbitrary URIs via the CurrentURI field of SetAVTransportURI without validating the scheme, host, or media legitimacy. Attackers can supply schemes such as http://, file:///data/misc/wifi/, rtsp://, or smb:// to have the TV fetch and render attacker-controlled content after a one-time DLNA pairing, enabling phishing pages, fake firmware prompts, and fake emergency alerts to be displayed, with subsequent commands executing silently.7h CVE-2026-1239946.3 MÉD

——0Hisense VIDAA Smart TV firmware V0000.01.00a.P0220 contains an unauthenticated access vulnerability in the DIAL (Discovery and Launch) service on TCP port 56789, which accepts control requests from any LAN-adjacent device without authentication, pairing, or user notification. Attackers can query running application states, enumerate installed applications via HTTP response codes, terminate active sessions with a DELETE request, and launch applications or bypass YouTube's Origin check by spoofing the Origin header to disclose viewing activity and subscriptions or disrupt device functionality.7h CVE-2026-890177.5 ALT

——0Skyline DataMiner BrokerGateway contains an embedded API key vulnerability that allows unauthenticated attackers to retrieve the installation-specific BrokerGateway key even while pairing mode is disabled. Attackers can use the retrieved key to obtain the unrestricted DataMinerUser.creds NATS credential and gain trusted message-bus access via TCP port 4222 without any prior DataMiner credentials. Fixed in DataMiner 10.6.9 CU1, 10.6.0 CU7, 10.5.0 CU19, and 10.4.0 CU22.8h
