CVE-2026-24207: NVIDIA Triton Inference Server Auth Bypass Enables Pre-Auth RCE on SageMaker (CVSS 9.8)

Integer overflow in the DALI backend of NVIDIA Triton Inference Server allows authenticated remote attackers to trigger memory corruption that may result in code execution, data tampering, or denial of service. The flaw requires low-level privileges plus user interaction (CVSS 8.0, AV:N/AC:L/PR:L/UI:R) and affects deployments exposing the DALI inference pipeline. No public exploit identified at time of analysis.

Authentication bypass in NVIDIA Triton Inference Server allows remote unauthenticated attackers to circumvent access controls, potentially leading to privilege escalation, denial of service, or information disclosure. With a CVSS 7.3 score and network-reachable attack vector (AV:N/AC:L/PR:N/UI:N), the flaw is exploitable without user interaction or credentials, though no public exploit identified at time of analysis. The vulnerability is not currently listed in CISA KEV, and EPSS data was not provided in the source intelligence.

Out-of-bounds read in the DALI backend of NVIDIA Triton Inference Server allows authenticated remote attackers to trigger memory disclosure that may escalate to code execution, data tampering, or denial of service. The flaw carries a CVSS 8.0 (High) rating reflecting low-privilege network access with required user interaction, and no public exploit identified at time of analysis. NVIDIA has published a security bulletin addressing the issue.

Uncontrolled resource consumption in NVIDIA Triton Inference Server's DALI backend allows a network-adjacent, low-privileged attacker to exhaust server resources, resulting in denial of service. The vulnerability (CWE-400) is triggered through the DALI data-loading and augmentation backend, requires low privileges and user interaction, and carries a CVSS score of 5.7 (Medium). No public exploit code or CISA KEV listing has been identified at time of analysis, placing this in a monitored-but-not-critical-urgency tier for most deployments.

Path traversal exploitation in NVIDIA Triton Inference Server enables unauthenticated remote attackers to cause denial of service by submitting crafted requests containing malicious path components. The CVSS vector (AV:N/AC:L/PR:N/UI:N) confirms zero authentication or user interaction is required, making this broadly reachable from the network with low attack complexity. No public exploit code has been identified and the vulnerability is not listed in the CISA KEV catalog at time of analysis; however, the no-prerequisite attack profile warrants patching per NVIDIA's advisory at nvidia.custhelp.com.

Denial of service in NVIDIA Triton Inference Server can be triggered remotely by unauthenticated attackers via an integer overflow condition (CWE-190). The CVSS 7.5 score reflects high availability impact with no confidentiality or integrity loss, and no public exploit has been identified at time of analysis. Defenders running Triton in network-exposed inference deployments should prioritize patching since exploitation requires no privileges, no user interaction, and low attack complexity.

Denial of service in NVIDIA Triton Inference Server can be triggered remotely without authentication via a path traversal flaw (CWE-22), enabling unauthenticated network attackers to disrupt model-serving availability. The CVSS 7.5 score reflects high availability impact with no confidentiality or integrity loss, and no public exploit has been identified at time of analysis.
