CVE-2026-47627Network attack vectorHinoki check available

Unauthenticated service interrupt via path traversal

Published Aug 18, 2026 · Updated Aug 20, 2026

Path traversal in NVIDIA Triton Inference Server for Linux before 26.06 allows remote attackers to interrupt service via crafted path input. NVIDIA's public fix notes attribute the issue to model environment unpacking and file-path handling that needed hardening against traversal, but no deeper per-function locus or exploit path has been published. The issue is scored as network-reachable with no privileges or user interaction, so exposed Triton deployments through 26.05 merit prompt triage, although NVIDIA has only published denial-of-service impact details.
