Dify version 1.14.1 and prior are affected by an unauthenticated path traversal in the Plugin Daemon icon proxy endpoint. The /console/api/workspaces/current/plugin/icon endpoint requires no authentication and passes the filename query parameter unsanitized into the internal Plugin Daemon REST API URL. Using ../ dot-sequence traversal an attacker escapes the authorized plugin/{tenant_id}/asset/ namespace and reaches arbitrary internal Plugin Daemon endpoints. The /health/check endpoint is always available and returns Plugin Daemon version, build time and pool status confirming exploitation.
