CVE-2026-24207Network attack vector

Unauthenticated code execution via restricted-API bypass

Published May 20, 2026 · Updated May 20, 2026

Authentication bypass in NVIDIA Triton Inference Server before r26.03 allows remote attackers to reach restricted model-management APIs. The SageMaker frontend fails to propagate restricted-API settings and omits authorization checks on its /models handlers. SageMaker and HTTP restrictions must be enabled; remote attackers can enumerate, load, or unload models, while code execution requires model files on a Triton-readable local path.
