What is CVE-2026-34082?

The Dify platform, an open-source development environment for LLM applications, contains a significant vulnerability in its authorization mechanisms. Specifically, the API method DELETE /console/api/installed-apps/<appId>/conversations/<conversationId> did not enforce proper authorization checks prior to version 1.13.1. This oversight permitted any authenticated user of Dify to delete the chat history of other users, potentially leading to unwanted data loss and privacy breaches. The issue was resolved in version 1.13.1, which reinforces authorization checks to safeguard users’ data.

Affected Version(s)
