Overview
The vulnerability, identified as CVE-2025-43862, affects the Dify open-source LLM app development platform. Prior to version 0.6.12, a critical access control flaw allowed non-admin users to access and modify the APP orchestration, leading to potential system compromise or data leakage. This issue is significant as it exposes system sensitive information to unauthorized users, impacting both data integrity and confidentiality.

How the Exploit Works
The exploit targets the improper access controls in Dify’s APP orchestration. A user without admin privileges is able to access and modify the APP orchestration due to lax access control mechanisms, even if the web UI for the APP orchestration is not presented to them. This can lead to unauthorized access and changes on the APPs, potentially compromising the system or leading to data leakage.
Conceptual Example Code
In a conceptual scenario, an attacker might send a request similar to the following to access and modify the APP orchestration:
POST /app-orchestration/modify HTTP/1.1
Host: target.example.com
Content-Type: application/json
User: non-admin user
{ "app_id": "1234", "new_configuration": {...} }This example demonstrates how a non-admin user could potentially make changes to the APP orchestration, leading to unauthorized modifications.
Please note: this is a hypothetical and simplified example, and actual exploitation of the vulnerability might require more complex interactions with the system.
