HIGH 8.1

Published 2026-10-13 · Last modified 2026-10-13

NVIDIA AIStore for Linux contains a path traversal vulnerability in the target-side object rename handler, where an unauthenticated remote attacker could cause an improper limitation of a pathname to a restricted directory by submitting a crafted rename destination directly to an AIStore target, resulting in the arbitrary creation or overwrite of a file. A successful exploit of this vulnerability might lead to code execution, escalation of privileges, information disclosure, data tampering, and denial of service.
