CVE-2026-41947 is an authorization bypass vulnerability in Dify before version 1.14.2 affecting the tracing subsystem used for profiling, monitoring, and logging application messages and model responses. The flaw is caused by missing tenant ownership validation in trace configuration endpoints, allowing an authenticated user with editor-level access to set and enable tracing for applications outside their own tenant. By abusing these endpoints, an attacker can register an attacker-controlled LLM trace provider for a victim application and hijack its tracing configuration. In multi-tenant deployments, this breaks tenant isolation and enables cross-tenant interception of application traffic. Publicly accessible applications are especially exposed because an attacker can access them as a client and then manipulate tracing configuration despite lacking legitimate ownership of the target application.
