CVE-2025-33253
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 an attacker could cause remote code execution by convincing a user to load a maliciously crafted file. A successful exploit of this vulnerability might lead to code execution, denial of service, 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 vulnerability where loading a maliciously crafted file can trigger remote code execution. An attacker would need to convince a user to load the crafted file, potentially leading to code execution, denial of service, information disclosure, or data tampering.

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.
-
Determine installed NeMo Framework versionRun 'pip show nemo' or 'pip list | grep -i nemo' to see the installed version. Alternatively, import nemo and print nemo.__version__Affected if The installed version is below 2.6.1
-
Verify NeMo package installationConfirm the nemo package is installed by checking import nemo succeeds. Run: python -c 'import nemo; print(nemo.__version__)'Affected if NeMo is installed and the version is less than 2.6.1
-
Check for file loading capabilityReview if your NeMo deployment allows loading external files via APIs such as nemo.import_from_*, model.restore, or config loading functions. Look for code paths that accept file paths as inputAffected if The environment accepts user-supplied or untrusted file paths for loading into NeMo
You are affected if NeMo Framework is installed at a version lower than 2.6.1 and your application loads files from sources that could be untrusted or unverified.
Generated from the published advisory. Verify against your own configuration.
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
Users should avoid loading untrusted or unverified files into the NeMo Framework. Apply security updates from NVIDIA when available and implement file validation/sandboxing for file loading operations.
NeMo Framework 2.6.1
- 1. Identify all systems running NVIDIA NeMo Framework versions prior to 2.6.1
- 2. Review the NeMo Framework release notes for version 2.6.1 to confirm the security fix addresses CVE-2025-33253
- 3. Create a backup of current configurations and any custom trained models
- 4. Upgrade the NeMo Framework installation to version 2.6.1 or later
- 5. Validate that the upgrade completed successfully by checking the installed version
- 6. Test critical model loading workflows to ensure functionality is preserved
- 7. Monitor for any unusual behavior during and after the upgrade process
