CVE-2026-47627: CWE-22 Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') in NVIDIA Triton Inference Server
CVE-2026-47627 is a critical path traversal vulnerability in NVIDIA Triton Inference Server for Linux version 0.0-26.05. This flaw allows an attacker to improperly limit pathname access, potentially leading to denial of service. The vulnerability has a high CVSS score of 9.8, indicating severe impact on confidentiality, integrity, and availability.
AI Analysis
Technical Summary
NVIDIA Triton Inference Server for Linux version 0.0-26.05 contains a CWE-22 path traversal vulnerability. An attacker could exploit this flaw to access restricted directories by manipulating file pathnames. Successful exploitation may cause denial of service conditions. The CVSS 3.1 base score is 9.8 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H), reflecting network attack vector, low attack complexity, no privileges or user interaction required, and high impact on confidentiality, integrity, and availability.
Potential Impact
Exploitation of this vulnerability could allow an unauthenticated attacker to traverse directories and potentially disrupt the service, causing denial of service. The high CVSS score indicates that confidentiality, integrity, and availability could all be severely impacted.
Mitigation Recommendations
No patch or official fix information is provided. Patch status is not yet confirmed — check the NVIDIA vendor advisory for current remediation guidance. Until a fix is available, restrict network access to the Triton Inference Server and monitor for suspicious activity related to path traversal attempts.
