Researchers Detail DifyTap Flaws in Dify That Could Expose AI Chats Across Tenants

Researchers discovered four vulnerabilities in Dify, an open-source platform for building AI workflows, that could let attackers read private AI conversations from other customers without logging in. These flaws, called DifyTap, exploited missing permission checks to expose chat messages across different customer accounts (called cross-tenant impact, where one customer's data leaks to another) and allowed unauthorized access to uploaded files and internal system APIs.
