CVE-2025-0649Public exploitNetwork attack vector

Server crash via recursive JSON processing

Published May 6, 2025 · Updated May 6, 2025

Stack exhaustion in TensorFlow Serving 2.18.0 and earlier allows remote attackers to crash inference servers via nested JSON requests. The REST JSON tensor path recursively parses deeply nested structures and stringifies invalid values for error reporting, exhausting the process stack. An unauthenticated request to a reachable prediction endpoint can terminate the ModelServer process and interrupt all hosted inference.
