Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
NVIDIA Triton Inference Server contains a vulnerability in the DALI backend where an attacker may cause an improper input validation issue. A successful exploit of this vulnerability may lead to code execution.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · moderate confidence

NVIDIA Triton Inference Server contains an improper input validation vulnerability in its DALI backend. Attackers can exploit this to achieve code execution on the inference server. The vulnerability stems from insufficient validation of inputs processed through the DALI (NVIDIA Data Loading Library) pipeline, allowing malicious input to trigger arbitrary code execution.

MitigationApply NVIDIA security patches for Triton Inference Server when released. Until then, restrict network access to Triton Inference Server endpoints and implement input sanitization at the application layer. Consider disabling the DALI backend if not required.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Identify Triton Inference Server version
    Run 'tritonserver --version' from the command line, or check the Docker image tag if running in a container. Alternatively, query the server metrics endpoint at /metrics to locate the version string.
    Affected if Version is lower than 25.07
  2. Confirm DALI backend is enabled
    Review Triton configuration files (config.pbtxt) for model pipelines. Look for 'dali' or 'DALI' in the backend configuration section, or check if any models use the DALI executor type.
    Affected if DALI backend is loaded or any DALI-based model pipeline is configured in the environment
  3. Assess network exposure
    Verify if the Triton Inference Server API endpoints (typically port 8000 for HTTP, port 8001 for gRPC) are exposed to untrusted networks or directly to the internet.
    Affected if Server is reachable from untrusted networks without proper network segmentation or authentication

Environment is affected if Triton Inference Server version is below 25.07 and the DALI backend is in use, allowing remote attackers to execute arbitrary code via crafted DALI pipeline inputs.

Interim mitigation

Apply NVIDIA security patches for Triton Inference Server when released. Until then, restrict network access to Triton Inference Server endpoints and implement input sanitization at the application layer. Consider disabling the DALI backend if not required.

Recommended fix High confidence

Triton Inference Server 25.07 or later

  1. 1. Identify current Triton Inference Server version by checking the deployed image or binary version
  2. 2. Stop or scale down Triton Inference Server instances
  3. 3. Pull the updated Triton Inference Server image with version 25.07 or later from NVIDIA's container registry
  4. 4. Update deployment manifests to reference the new version (e.g., nvcr.io/nvidia/tritonserver:25.07-py3 or later)
  5. 5. Verify the new image version matches or exceeds 25.07
  6. 6. Restart Triton Inference Server with the updated image
  7. 7. Validate that Triton Inference Server starts successfully and the DALI backend is operational
  8. 8. Test inference workflows to confirm normal operation
Caveat No specific breaking changes documented for this security update; standard upgrade testing recommended
