Official Description

Dify version 1.14.1 and prior contains an authorization bypass vulnerability that allows authenticated editor users to set and enable trace configurations for any application regardless of tenant ownership. Attackers can exploit missing tenant ownership checks in the trace configuration endpoints to redirect all messages and responses from victim applications to attacker-controlled LLM trace providers. NOTE: Dify Cloud allows unauthenticated free self-registration, making account creation trivially accessible to any attacker.

Risk Analysis

This critical authorization bypass vulnerability in Dify allows authenticated editor users to configure tracing for any application, regardless of tenant ownership. Attackers can redirect victim application messages to their own LLM trace providers due to missing tenant ownership checks. With a CVSS score of 9.1, this is a serious concern, particularly as Dify Cloud enables easy account creation.

No public exploit is currently known for this vulnerability. The flaw is remotely exploitable and requires authentication, though Dify Cloud's free self-registration makes obtaining credentials trivial.

Recommended Action

Upgrade Dify to a version beyond 1.14.1 to resolve the authorization bypass. Ensure that all trace configuration endpoints properly enforce tenant ownership checks.
