Unauthenticated code execution via heap buffer overflow
Published Jul 14, 2026 · Updated Jul 14, 2026
Heap-based buffer overflow in Minecraft Bedrock Dedicated Server allows remote attackers to execute code over a network. Microsoft has not disclosed the affected component or the operation that writes beyond the heap allocation. No authentication or user interaction is required, and successful exploitation executes arbitrary code in the server process.
