Technical details
The vulnerability exists in NeMo's dataset-loading workflow where user-supplied model_config.yaml files are processed without adequate validation, allowing unsafe parameter injection. An attacker can craft a malicious configuration file to achieve code execution, data modification, denial of service, or information disclosure. The attack requires an attacker to provide a crafted model configuration that a user or system loads, but does not require prior authentication.
