CVE-2024-43488 is a critical remote code execution vulnerability in the Visual Studio Code extension for Arduino. The available description states that the flaw is caused by missing authentication for a critical function, allowing an unauthenticated attacker to reach privileged functionality over a network attack vector and execute code remotely in the context of the extension/user environment. Public reporting further indicates the extension is deprecated, will not receive a fix, and existing installations remain vulnerable.
