Matthew Panzerino, TechCrunch:

Apple has disabled the Apple Watch Walkie Talkie app due to an unspecified vulnerability that could allow a person to listen to another customer’s iPhone without consent, the company told TechCrunch this evening.

Apple’s statement:

We were just made aware of a vulnerability related to the Walkie-Talkie app on the Apple Watch and have disabled the function as we quickly fix the issue. We apologize to our customers for the inconvenience and will restore the functionality as soon as possible. Although we are not aware of any use of the vulnerability against a customer and specific conditions and sequences of events are required to exploit it, we take the security and privacy of our customers extremely seriously. We concluded that disabling the app was the right course of action as this bug could allow someone to listen through another customer’s iPhone without consent. We apologize again for this issue and the inconvenience.

Sounds like this is a temporary stoppage until they can get a workaround to the vulnerability.

Does anyone reading this use the Walkie-Talkie app? If so, ping me, I’m interested in the use case.
