Has this flaw been fixed?

@ptegler

now I stumble on the bluetooth backdoor found in ALL ESP devices!

Are you sure it is a backdoor and are your certain my esp8266’s are affected?

@ptegler

gotta’ believe, as well as appreciate… what people believe.

People believe about every lie and even build cults/religions based on them Paul

Espressif has also put out a response to cover this: Espressif’s Response to Claimed Backdoor and Undocumented Commands in ESP32 Bluetooth Stack | Espressif Systems

Highlights:

No Remote Access: They cannot be triggered by Bluetooth, radio signals, or over the Internet, meaning they do not pose a risk of remote compromise of ESP32 devices.
Security Impact: While these debug commands exist, they cannot, by themselves, pose a security risk to ESP32 chips. Espressif will still provide a software fix to remove these undocumented commands.
Scope: If ESP32 is used in a standalone application and not connected to a host chip that runs a BLE host, the aforementioned HCI commands are not exposed and there is no security threat.
