Mooncake transfer engine before 0.3.12 contains an out-of-bounds read vulnerability in the readString function of include/common.h that allows unauthenticated attackers to crash the service by sending a zero-length handshake frame. Attackers can connect to the handshake port listening on all interfaces and send an eight-byte frame to terminate the hosting process, such as an SGLang inference server.
