ruvnet merged three critical pull requests yesterday addressing security and stability issues across the platform.
The most significant change was pull request 623, which fixed a critical OTA upload vulnerability. Previously, ESP32 nodes with no provisioned PSK accepted firmware uploads from any host over plain HTTP - essentially allowing attackers to brick or backdoor devices with a single network call. The fix changes the…
Pull request 621 resolved a WebSocket broadcast issue where the sensing server displayed incorrect connection status. After ESP32 nodes lost power or network connectivity, the UI continued showing "LIVE - ESP32 HARDWARE Connected" with frozen data. The fix now correctly switches to "esp32:offline" status within five…
Pull request 628 wrapped up ESP32-S3 firmware version 0.6.5, addressing a Timer Service stack overflow that caused boot loops on fresh builds. The issue stemmed from a missing configuration in the canonical build file that set the FreeRTOS timer task stack depth to 8KB instead of the insufficient 2KB default.
All fixes underwent end-to-end hardware validation on COM7 with ESP32-S3 8MB modules. The…
