## Technical details

The vulnerability is a path traversal flaw in NVIDIA Triton Inference Server for Linux that allows an attacker to bypass path validation controls and access files outside the intended directory structure. The root cause is insufficient input validation on file paths, enabling absolute path traversal attacks. An attacker with local access to the server can exploit this by specifying absolute paths in API requests or configuration parameters to read arbitrary files or potentially write malicious content. The vulnerability could lead to information disclosure (reading sensitive model files, configuration data, or system files) or code execution if combined with other attacks. Patches are available from NVIDIA in security bulletin 5865 released in August 2026.
