NVIDIA has released an important security update addressing a high-severity vulnerability in its NeMo Curator tool. The flaw, tracked as CVE-2025-23307, could enable attackers to execute arbitrary code, escalate privileges, and compromise sensitive data if exploited.
According to the security bulletin, “NVIDIA NeMo Curator for all platforms contains a vulnerability where a malicious file created by an attacker could allow code injection. A successful exploit of this vulnerability might lead to code execution, escalation of privileges, information disclosure, and data tampering.”
The flaw carries a CVSS base score of 7.8 (High) with significant impact ratings for confidentiality, integrity, and availability.
If exploited, attackers could weaponize a specially crafted file to inject malicious code directly into NeMo Curator environments. This could allow:
- Remote Code Execution (RCE)
- Privilege Escalation
- Sensitive Information Disclosure
- Tampering with AI datasets and outputs
Given NeMo Curator’s role in handling and filtering data for AI and large language model (LLM) training pipelines, the risks extend beyond typical endpoint compromise. Malicious manipulation of training data could poison AI models, leading to subtle yet far-reaching impacts across AI-driven workflows.
The bulletin confirms that the vulnerability affects all versions of NVIDIA NeMo Curator on Windows, Linux, and macOS prior to version 25.07. NVIDIA has released Curator 25.07 as the patched version that addresses this issue.
