dify: Improper Access Control
CVE-2025-43862 is a high-severity improper access control vulnerability in dify from LangGenius, with a CVSS 3.1 base score of 7.6 out of 10. It can be exploited remotely over the network by an attacker with a low-privileged account, without any action from a user. Affected dify versions: < 0.6.12. The record does not name a fixed version, so check the vendor advisory. There is no confirmed exploitation so far. EPSS estimates a 0.34% chance of exploitation within 30 days, which is low compared with other CVEs.
High severity with no evidence of exploitation so far.

Official description
Dify is an open-source LLM app development platform. Prior to version 0.6.12, a normal user is able to access and modify APP orchestration, even though the web UI of APP orchestration is not presented for a normal user. This access control flaw allows non-admin users to make unauthorized access and changes on the APPSs. This issue has been patched in version 0.6.12. A workaround for this vulnerability involves updating the the access control mechanisms to enforce stricter user role permissions and implementing role-based access controls (RBAC) to ensure that only users with admin privileges can access Orchestration of the APPs.

The underlying weakness: Improper Access Control
The product does not restrict or incorrectly restricts access to a resource from an unauthorized actor.
How developers prevent this class of flaw
- Very carefully manage the setting, management, and handling of privileges. Explicitly manage trust zones in the software.
- Compartmentalize the system to have safe areas where trust boundaries can be unambiguously drawn. Do not allow sensitive data to go outside of the trust boundary and always be careful when interfacing with a compartment outside of the safe area. Ensure that appropriate compartmentalization is built into the system design, and the compartmentalization allows for and reinforces privilege separation functionality. Architects and designers should rely on the principle of least privilege to decide the appropriate time to use privileges and the time to drop privileges.
