One television. Multiple exposed services. A shared security boundary: the local network.

🔎 Research at a Glance
This repository documents six security findings identified during independent security testing of a Hisense VIDAA Smart TV . The research examines how network-accessible automation, discovery, media playback, remote-control, and messaging interfaces may allow a network-adjacent actor to interact with the television without adequate authentication or authorization.
The observed consequences span browser-context JavaScript execution, application-data exposure, on-screen content manipulation, remote app control, denial of service, and TV control-plane weaknesses .
Scope: Results are based on the specific device and firmware tested. They should not be assumed to affect every Hisense television or VIDAA release without additional verification.

What makes these findings significant?
Confidentiality: The WebDriver finding includes demonstrated extraction of JavaScript-accessible TV data and receipt of that data at an external HTTP endpoint.
Integrity: Network-accessible control interfaces can alter the viewer's experience through application control, browser UI changes, media presentation, or volume adjustment.
Availability: My SOAP flooding test rendered the television completely unresponsive until I physically disconnected and reconnected its power supply.
Authentication boundaries: Several interfaces rely on absent, shared, incomplete, or inconsistently enforced authorization mechanisms. Their requirements differ; not every finding is a zero-interaction exploit.
🕸️ Attack Surface Overview
Diagram note: This is a summary of distinct findings, not a single chained exploit. The prerequisites and degree of demonstrated control differ across services.

🧪 Evidence and Validation
Each individual finding is documented separately to preserve its specific attack prerequisites, observed behavior, and evidence. Supporting material includes, where applicable:
Network service responses and protocol-level test output.
On-device photographs of the television displaying researcher-controlled content.
Browser storage extraction and external webhook receipt.
Command execution and device-state verification logs.
Screenshots of authentication and consent behavior.
📬 Vendor Notification Timeline
Vendor status: As of 30 October 2026 , I have received no acknowledgement or response from Hisense since my initial notification on 27 April 2026.
This timeline documents my communications with Hisense. I have not received confirmation of the findings, a severity assessment, or remediation information from the vendor. I will update the advisories if a response becomes available.
🛡️ Security Recommendations
At a high level, vendors and integrators should consider:
Disable production exposure of debugging and automation services or restrict them to authenticated, explicitly enabled development environments.
Require device-specific authentication and authorization for remote-control, media, and application-management commands.
Enforce meaningful user consent before sensitive actions and ensure consent prompts actually block command execution until approval.
Rate-limit pairing attempts , bind pairing approval to a requesting client, and enforce lockouts or challenge expiration.
Harden UPnP/DLNA processing against untrusted requests and resource-exhaustion conditions.
Reduce unnecessary network exposure , use broker topic-level access controls, and protect communication with correctly validated TLS identities.
For owners and network administrators, isolating Smart TVs from untrusted LAN clients can reduce exposure while vendor fixes are unavailable.
⚖️ Responsible Research and Usage
This repository is published for defensive security research, vulnerability analysis, and responsible public disclosure following vendor notification. All testing was performed against a device under my control. Do not test systems without authorization.
No universal exploitability claim is made: The documented results apply to the tested configuration unless additional affected versions are established.
📺 Smart TVs are computers on your network — their control interfaces deserve the same security scrutiny.
