CVE-2026-50756Network attack vector

Data disclosure via provider-based SSRF guard bypass

Published Jul 21, 2026 · Updated Jul 21, 2026

SSRF in DayuanJiang next-ai-draw-io 0.4.13 allows remote attackers to disclose conversation data via crafted provider headers. The getAIModel guard in lib/ai-providers.ts trusts the client-controlled x-ai-provider header and exempts EdgeOne or default Ollama requests with a custom base URL but no API key. An unauthenticated HTTP request can redirect the server's chat completion call, exposing the system prompt, user messages, and diagram XML to an attacker-controlled endpoint.
