CVE-2025-23250
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 an improper limitation of a pathname to a restricted directory by an arbitrary file write. A successful exploit of this vulnerability might lead to code execution 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 path traversal vulnerability (improper limitation of pathname to restricted directory) that allows an attacker to write arbitrary files outside intended directories. This arbitrary file write capability can be leveraged to achieve code execution and 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.
-
Identify NeMo Framework versionRun 'pip show nemo' or use your Python package manager to check the installed NeMo versionAffected if Installed version is below 25.02
-
Audit file write operations in custom codeReview any code that uses NeMo for file input/output operations, particularly where user-supplied paths or dynamic path construction is involvedAffected if File write operations exist without proper path validation logic
-
Verify path validation implementationInspect the file handling code in your NeMo deployment to confirm it uses canonical path resolution and validates the final resolved path stays within allowed directories before any write operationsAffected if Path validation is absent or incomplete in file write functionality
You are affected if your NeMo version is below 25.02 and any component performs file writes without proper path traversal protection.
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 · scoped25.02
Implement strict path validation that canonicalizes paths and verifies the final resolved path stays within allowed directories before any file write operations; restrict file write permissions to specific safe directories.
25.02 or later
- 1. Back up your current NeMo installation, models, and any custom configurations or data
- 2. Stop any running NeMo services, training jobs, or inference processes
- 3. Upgrade NeMo by running: pip install --upgrade nemo-framework
- 4. Alternatively, install the specific fixed version: pip install nemo-framework==25.02 or later
- 5. Verify the installation succeeded by running: import nemo; print(nemo.__version__)
- 6. Ensure the version is 25.02 or higher
- 7. Restart any NeMo services or recreate your runtime environments
