Summary
Dify before version 1.14.2 contains an authorization bypass vulnerability that allows authenticated editor users to set and enable trace configurations for any application regardless of tenant ownership. This vulnerability allows attackers to redirect all messages and responses from victim applications to attacker-controlled LLM trace providers.
Risk Assessment
Organizations may be exposed to data takeover and application manipulation, leading to serious security breaches. The lack of tenant ownership checks creates additional risks for user data.
Recommendation
It is recommended to update Dify to version 1.14.2 or later to eliminate this vulnerability. Additionally, implementing further access controls and monitoring user account registrations is advisable.
Original NVD description (English source)
Dify before version 1.14.2 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.
