AI developers working with Nvidia tools Megatron Bridge or NeMo Framework should update their applications promptly. Several security vulnerabilities have been closed in recent versions.
Various Dangers
Nvidia's NeMo Framework is used for managing AI agents. As indicated in a warning message, developers have closed a total of ten vulnerabilities. All loopholes (e.g., CVE-2025-33245) are classified as "high" threat level, and remote attacks are possible. Following successful attacks, attackers have multiple doors open, allowing them to gain higher user privileges or even execute malicious code. How attacks could proceed is not yet known.
All platforms are reportedly affected. Developers assure that the security issues have been resolved in version 2.6.1. According to them, all previous versions are vulnerable.
Megatron Bridge is used for AI training. Here, in two cases (CVE-2025-33239 "high", CVE-2025-33240 "high"), errors can occur due to insufficient input validation, as the developers explain in a post. In the worst-case scenario, this allows malicious code to enter and compromise systems. All platforms are affected by this. Version 0.2.2 provides a solution. Newer versions are vulnerable.
So far, there are no reports of attackers already targeting Nvidia's two AI tools. However, since this can change quickly, administrators should not postpone patching.
