Tutorials of Terror: How NVIDIA’s AI Training Guides Became a Gateway for Code Injection
Ddos 
NVIDIA has released a critical software update for its Megatron Bridge, a key component used in training large language models (LLMs). The bulletin discloses two high-severity vulnerabilities hidden in an unlikely place: the software’s tutorials.
The flaws, tracked as CVE-2025-33239 and CVE-2025-33240, allow attackers to perform code injection attacks. These vulnerabilities stem from “data merging” and “data shuffling” tutorials included with the software, proving that sample code can carry production-level risks.
The vulnerabilities are nearly identical in nature but reside in different parts of the educational materials provided with the bridge. Both issues arise from improper input handling (CWE-94) in scripts intended to teach users how to manipulate data.
According to the security bulletin, “NVIDIA Megatron Bridge contains a vulnerability in a data merging tutorial, where malicious input could cause a code injection.”
A second vulnerability affects the “data shuffling” tutorial, carrying the same risk profile. While tutorials are often overlooked by security teams, in the context of AI infrastructure—where vast datasets are processed automatically—a vulnerability in data handling scripts can be critical.
Despite originating in tutorial components, the impact of these flaws is severe. Both vulnerabilities carry a CVSS Base Score of 7.8 (High).
If an attacker with local access to the system can feed malicious input into these components, they can break out of the intended operation and execute their own commands.
“A successful exploit of this vulnerability might lead to code execution, escalation of privileges, information disclosure, and data tampering,” the advisory warns.
This “escalation of privileges” is particularly dangerous in AI environments, where computing resources are powerful and often have access to massive proprietary datasets.
The advisory notes that the attack vector is Local (AV:L), meaning the attacker needs a foothold on the system to exploit these flaws. However, the complexity of the attack is Low (AC:L), and it requires only Low Privileges (PR:L). This makes it an ideal avenue for an insider threat or a malware strain that has already gained a low-level entry point and is looking to pivot to root access.
NVIDIA has released software updates to address these flaws. Administrators and developers using NVIDIA Megatron Bridge are urged to update their installations immediately.
