{"id":"CVE-2025-59422","summary":"Dify Has Broken Access Control on Log Message Endpoint Allows Reading of Chats of Others","details":"Dify is an open-source LLM app development platform. In version 1.8.1, a broken access control vulnerability on the /console/api/apps/\u003cAPP_ID\u003echat-messages?conversation_id=\u003cCONVERSATION_ID\u003e&limit=10 endpoint allows users in the same workspace to read chat messages of other users.
