CVE-2025-33236
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 created by an attacker could cause code injection. 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 confidenceCode injection vulnerability in NVIDIA NeMo Framework where attacker-controlled malicious data can be processed in an unsafe manner, potentially leading to arbitrary code execution, privilege escalation, information disclosure, 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 installationRun 'pip show nemo' or 'pip show nemo-framework' to retrieve installed package information, or check your environment's package manifestAffected if Package is installed and version cannot be determined or is below 2.6.1
-
Verify exact installed versionExtract the 'Version:' field from the package metadata obtained in the previous stepAffected if Version number is less than 2.6.1 (for example: 2.6.0, 2.5.0, 1.x.x)
-
Confirm data processing scopeReview your NeMo deployment configuration to determine if the framework processes external, untrusted, or user-supplied data files, model configurations, or training inputsAffected if The framework processes any attacker-controlled input data and the installed version is below 2.6.1
You are affected if your installed NVIDIA NeMo Framework version is below 2.6.1 and the framework processes external or untrusted data.
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
Implement strict input validation and sanitization for all data processed by the framework; apply principle of least privilege to limit impact of successful exploitation.
2.6.1
- 1. Backup any existing Nemo installations, models, and configuration files
- 2. Identify the current Nemo installation method (pip, conda, or source)
- 3. If using pip, run: pip install --upgrade nemo-toolkit==2.6.1
- 4. If using conda, run: conda install -c nvidia nemo-toolkit=2.6.1
- 5. If installed from source, pull the v2.6.1 tag and rebuild: git fetch origin && git checkout v2.6.1 && pip install -e .
- 6. Verify the installed version matches 2.6.1: python -c "import nemo; print(nemo.__version__)"
- 7. Test that critical NeMo functionality works as expected after upgrade
- 8. Review NeMo 2.6.1 release notes for any required migration steps or configuration changes
