Unauthenticated information disclosure via oversized inference request
Published Aug 6, 2025 · Updated Aug 6, 2025
Information disclosure in NVIDIA Triton Inference Server before 25.07 allows remote attackers to expose an internal shared-memory name. The Python backend returns its private IPC shared-memory region name in an error after an oversized inference request exceeds the memory-pool limit. No authentication or user interaction is required on an exposed inference endpoint; this flaw alone reveals the region name, while separate flaws are needed for memory access or code execution.
