Arbitrary Code Execution Vulnerability in Dify by Langgenius

CVE-2025-3466

What is CVE-2025-3466?

Versions 1.1.0 to 1.1.2 of Dify by Langgenius contain a vulnerability that allows unsanitized input in the code node. This issue permits the execution of arbitrary code with elevated permissions, exposing the system to serious security risks. Malicious actors can override critical global JavaScript functions, such as parseInt, bypassing established sandboxing security measures. Consequently, this enables unauthorized access to sensitive data, including secret keys and internal network servers, facilitating lateral movement within the system. The vulnerability has been addressed in version 1.1.3.
