A flaw in Amazon's Alexa smart home devices could have allowed hackers access to personal information and conversation history, cyber-security researchers say.
Attackers could install or remove apps on a device without the owner knowing, Check Point Research reports.
The hack "required just one click on an Amazon link" purposely crafted by the attacker, it says.
The firm told Amazon about the flaw, which has now been fixed.
Amazon said: "The security of our devices is a top priority, and we appreciate the work of independent researchers like Check Point who bring potential issues to us."
It said it did not know of any case where a bad actor had used the vulnerability to target its customers.
In January, Amazon said there were "hundreds of millions" of Alexa devices in the world.
