langgenius/dify: Insufficient Isolation of System-Dependent Functions
CVE-2025-3466 is a high-severity insufficient isolation of system-dependent functions vulnerability in langgenius/dify from LangGenius, with a CVSS 3.1 base score of 7.2 out of 10. It can be exploited remotely over the network by an attacker with administrator privileges, without any action from a user. The record lists version 1.1.3 as the first without the flaw, so updating langgenius/dify to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.83% chance of exploitation within 30 days, higher than 58% of scored CVEs.
High severity with no evidence of exploitation so far.

Official description
langgenius/dify versions 1.1.0 to 1.1.2 are vulnerable to unsanitized input in the code node, allowing execution of arbitrary code with full root permissions. The vulnerability arises from the ability to override global functions in JavaScript, such as parseInt, before sandbox security restrictions are imposed. This can lead to unauthorized access to secret keys, internal network servers, and lateral movement within dify.ai. The issue is resolved in version 1.1.3.
