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.

langgenius dify: from 1.1.0 before 1.1.3 — fixed in 1.1.3

How to fix

Upgrade to a fixed version: langgenius dify 1.1.3. Check the vendor advisory for mitigations.
