Dify trace configuration authorization bypass
CVE-2026-41947 is an authorization bypass vulnerability in Dify before version 1.14.2 affecting the tracing functionality used for profiling, monitoring, and logging application messages and model responses. The vulnerable trace configuration endpoints fail to validate tenant ownership, allowing an authenticated editor user to set and enable trace configurations for arbitrary applications regardless of which tenant owns them. By abusing these missing tenant ownership checks, an attacker can register an attacker-controlled LLM trace provider for a victim application and cause the victim application's prompts, messages, responses, and chat history to be forwarded externally. Public reporting describes this as a tracing hijack that can be used against publicly accessible applications on the same Dify instance.
