| Package | Affected versions | Patched versions |

| esp-idf | ≤ 4.2 | |
| esp8266 nonos sdk | ≤ 3.0.3 | |
| esp8266 rtos sdk | ≤ 3.3 |
An encryption-bypass issue was discovered on Espressif ESP-IDF devices through 4.2, ESP8266_NONOS_SDK devices through 3.0.3, and ESP8266_RTOS_SDK devices through 3.3. Broadcasting forged beacon frames forces a device to change its authentication mode to OPEN, effectively disabling its 802.11 encryption.
