arduino-esp32 is an Arduino core for the ESP32, ESP32-S2, ESP32-S3, ESP32-C3, ESP32-C6 and ESP32-H2 microcontrollers. The arduino-esp32 CI is vulnerable to multiple Poisoned Pipeline Execution (PPE) vulnerabilities. Code injection in tests_results.yml workflow (GHSL-2024-169) and environment Variable injection (GHSL-2024-170). These issue have been addressed but users are advised to verify the contents of the downloaded artifacts.
