CVE-2026-41947: Authorization Bypass Through User-Controlled Key in langgenius dify
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.
AI Analysis
Technical Summary
CVE-2026-41947 is an authorization bypass vulnerability in langgenius dify versions prior to 1.14.2. Authenticated users with editor privileges can exploit missing tenant ownership checks in trace configuration endpoints to set and enable trace configurations for applications they do not own. This allows attackers to redirect all messages and responses from victim applications to attacker-controlled LLM trace providers. The vulnerability is particularly concerning because Dify Cloud permits unauthenticated free self-registration, making it trivial for attackers to create accounts and exploit this flaw.
Potential Impact
Attackers with authenticated editor access can bypass tenant ownership restrictions to manipulate trace configurations of any application, potentially redirecting sensitive application data to attacker-controlled endpoints. This compromises confidentiality and integrity of application communications. The ease of account creation on Dify Cloud increases the risk of exploitation.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict editor privileges to trusted users only and monitor for suspicious trace configuration changes. Review tenant ownership verification mechanisms in trace configuration endpoints.
