This underscores the principle that IoT devices should not be allowed to communicate over the public Internet. Pretty much all cheap, Chinese-made hardware of this kind has intentional or unintentional security holes waiting to be exploited.
Better to buy devices that can work without internet and just blacklist them at the router level. Price or origin is not a good metric to ensure no leaks.
Not doxing myself, but... Company with a known name vibecoded a dashboard with Claude. Which also hardcoded a password into the client-side of the dashboard, which I caught.
Honestly, I'd rather it leak my GPS to the Chinese government than the US government. They don't have jurisdiction over me anyway.
> should not be allowed to communicate over the public Internet
It would be a no-go for non-techies. One of the biggest draws to IoT devices for "average Joes" is being able to view and control them from remotely, and they aren't going to have the skills or know-how to set up a VPN correctly with dynamic DNS so that their phone can VPN into their home and then sideload/jailbreak their phone to load a custom app to control it. "It just works from anywhere" is a big sell for them.
There are better solutions, like Apple’s HomeKit. I’m able to watch a camera that has no internet access because it passed through my Apple TV, which serves as a home hub. I didn’t have to set any of this up, it just works when you have the required hardware.
HomeKit will take care of the VPN/remote access part, sure, but your devices still need to communicate with the HomeKit device, and that's usually over Wi-Fi, which puts the devices on the public internet, and carries the same security risk.
There are various non-internet protocols for IoT devices, none of them good:
* Zigbee: Requires some technical understanding to set up, devices randomly disconnect for hours even when they are 2ft from the coordinator, all-around horrible experience for non-techies
* Non-standard Zigbee variants: even worse
* Matter-over-Thread: horrendously designed from a UX perspective. Easy-to-lose barcodes stuck on cards in the packaging, weird 12-letter codes, and your non-techie cannot understand what the hell Matter or Thread is. Pairing is an absolute nightmare.
Requires no technical understanding. At least not more than e.g. a WIFI router.
> devices randomly disconnect for hours even when they are 2ft from the coordinator,
You present this like a fact. But it is at most an anecdote. I present you a different anecdote: I have ~30 zigbee devices, in two different houses (first a house with concrete floors and cellar and level 1..3) and now one old woodwork structure house with 2 floors. Nowhere did I had even half an hour of disconnection.
> all around-horrible
... excellent experience even for my ex-spouse, which is/was non-techie.
However, that you present Zigbee here at all is weird. Zigbee doesn't have any way to transport a camera stream. It's mean for low-powered battery devices. My temperature sensors got a 1500mAh AAA chargeable batteries and they lasts now for over one year. Note that I have sensors from ~ 15 different brands. Mostly battery powered sensors and mains power switchable plugs.
I also enjoy that these Zigbee devices are by design completely disconnected from any IP traffic. This, and their (intentional) low data rate make them almost impossible to misuse. E.g. as denial-of-service originators or amplifiers.
It's like you present WIFI as long-range thingy but actually you'd want LORA for that. I'm not assuming that knowing for what kind of usage a tech was designed as "needing technical understanding". After all, no one would claim "you need technical understanding" to know that you better use a truck instead of a Porsche Cayman to transport 50 cubic meters of sand.
> Nowhere did I had even half an hour of disconnection.
Well my garage door opener sensor has been disconnected for two 30 minute gaps today and my plant humidity sensors go offline for 2 weeks at a time.
So yeah, it's not ready for prime time.
> LORA
No, let's not even go there. Tech nerd protocol here that's an awkward middle ground that creates even more problems. Average Joes aren't going to set that crap up.
> I’m able to watch a camera that has no internet access because it passed through my Apple TV, which serves as a home hub.
How exactly does this prevent the same kind of issue for Apple devices? Aren't you just trusting that Apple handles your data better than TP-Link? Not saying they don't but routing through another device doesn't really add security on its own.
The report seems obviously AI generated, so I can't be bothered to read in its entirety, but based on my quick skim, "leaked home GPS" makes it sound worse than it is. Unless you're dumb enough to set DMZ on this device, this won't be exposed to the internet, and if it's LAN only, don't you already know the location? Even for a remote attacker who somehow got LAN access remotely, they can probably deduce the location through other means (eg. using crowdsourced wifi databases).
It sounds like you are blaming the user for providing data that a service can leak. That's like blaming a user for writing personal emails when faced with an email provider that leaks emails.
A random post on hacker news isn't going to make a dent in TP-Link's camera marketshare positive or negative. If the GP really has bad motives they wouldn't really accomplish anything with that. But I doubt they do. I use these cams myself too. They're ok if you limit their internet access. I limit all my TP-Link stuff anyway since they suddenly removed local access for their switched power plugs in an auto firmware update.
There is only two ways to receive this unencrypted data:
- to do the song and dance to allow the whole Internet to access this cam - and 'security professionals' have been advising no to do that no matter what vendor it is
- to sit on your wire, literally and sniff everything
Unencrypted personal data is not good but if you have a habit of leaving your car with the open doors, windows and a key in the ignition - don't run around telling horror stories what someone didn't close the lid on a cookie jar.
That's because you live in a shitty place where your can't do that with your car, and think that's normal. There are places in the world where you can just leave your car unlocked with cash sitting out, and no one steals it. Yeah, the Internet is not such a place, so we can't act that way here, but in the physical world, there are safe places where you can relax.
Six months of coordinated disclosure on a TP-Link Kasa camera resulted in two CVEs, a triage failure where the vendor described a vulnerability that doesn't exist in the reported payload, a beta patch that permanently bricked my test device, and a factory reset that doesn't clear previous owner data.
The GPS finding (CVE-2026-13230) has been publicly documented on this device class since 2020. A single UDP packet returns sub-meter home coordinates with no authentication required. TP-Link scored it 5.3 medium. My independent assessment is 7.1 high. Precise home coordinates aren't low confidentiality impact.
The credential finding (CVE-2026-9770) covers a fleet wide RSA key and unsalted MD5 TP-Link ID credentials. Same credentials provide global authentication across the TP-Link ecosystem.
Factory reset on a secondhand device doesn't clear the data. Connecting to the device's soft AP during setup and sending a single UDP packet returns the previous owner's GPS coordinates.
TP-Link is a prominent maker of network hardware, including home and mesh routers.
Why single out bad Chinese coding? Bad US IoT coding has a longer history.

I reckon security will be about the same.
Soon?
I've already seen multiple of TP-Link's firmware engineers leave their LLM history public and indexed by search engines.
It's quite obviously them as well.

I don't think that's normal. Like, to the point where I'm wondering if you have a bad opinion of the whole protocol because you got a faulty device.

When they get down to the $20 price point like the Chinese schlock, let me know, I'll be first in line to buy them.
It's not the best company but they're cheap.
AFAIK it was because it was an unencrypted protocol and you can just manually turn it back on in device settings.
