CVE-2025-33245
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 · uneditedNVIDIA NeMo Framework contains a vulnerability where malicious data could cause remote code execution. A successful exploit of this vulnerability might lead to code execution, escalation of privileges, information disclosure, and data tampering.
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 confidenceNVIDIA NeMo Framework contains a remote code execution vulnerability where maliciously crafted data can trigger code execution on the affected system. The vulnerability allows attackers to potentially execute arbitrary code, escalate privileges, disclose information, or tamper with data.

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 checksWork through these to decide whether this CVE applies to you.
-
Identify installed NeMo Framework versionRun `pip show nemo` or `pip show nemo-llm` to retrieve the installed version. Check the version number against the affected range: any version below 2.6.1 is potentially vulnerable.Affected if Installed version is lower than 2.6.1
-
Confirm NeMo processing pipeline is activeInspect running processes for NeMo-related services: look for processes containing 'nemo', 'nemo_framework', or related training/inference scripts. Use commands like `ps aux | grep -i nemo` or check running containers with `docker ps`.Affected if NeMo processes are running and actively handling data
-
Check network exposure of NeMo servicesReview firewall rules, network ACLs, or service bindings. Determine if NeMo API servers or inference endpoints are bound to 0.0.0.0 or exposed to untrusted networks. Use `netstat -tlnp` or `ss -tlnp` to identify listening ports associated with NeMo.Affected if NeMo services are accessible from untrusted network segments or the internet
-
Audit data ingestion pointsExamine NeMo configuration files, scripts, or environment variables that define data sources. Look for paths to untrusted or external data (HTTP URLs, shared network mounts, user-uploaded files). Check for absence of input validation in data loading code.Affected if NeMo is configured to accept data from untrusted or external sources without validation
A system is affected if NeMo Framework version is below 2.6.1 AND the framework is actively processing data from untrusted sources or is network-accessible.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scoped2.6.1
Apply NVIDIA's security patches when available; until then, restrict network access to NeMo Framework services and validate/sanitize all data inputs before processing.
Nemo 2.6.1
- 1. Identify the currently installed version of NVIDIA NeMo Framework by running: pip show nemo or conda list nemo
- 2. If the installed version is below 2.6.1, upgrade to version 2.6.1 using: pip install --upgrade nemo==2.6.1 or conda install nemo=2.6.1
- 3. Verify the upgrade was successful by checking the installed version again
- 4. Restart any running NeMo services or applications to ensure the updated version is loaded
