CVE-2026-56277— FlowiseAI Flowise 输入验证错误漏洞

Flowise - Hardcoded CORS Wildcard in TTS Endpoint

Flowise before 3.1.2 sets Access-Control-Allow-Origin to a hardcoded wildcard (*) on its text-to-speech (TTS) generation endpoint (packages/server/src/controllers/text-to-speech/index.ts), independent of the server's configured CORS policy. This bypasses the server's otherwise restrictive default CORS configuration (getCorsOptions()) and allows any webpage to make cross-origin requests that trigger TTS generation using stored credentials, enabling drive-by cross-origin credential abuse.

FlowiseAI Flowise 输入验证错误漏洞

FlowiseAI Flowise是FlowiseAI公司开源的一个用于轻松构建 LLM 应用程序的工具。 FlowiseAI Flowise 3.1.2之前版本存在输入验证错误漏洞，该漏洞源于在文本转语音（TTS）生成端点中将Access-Control-Allow-Origin设置为硬编码通配符，绕过了服务器的CORS配置，允许任何网页利用存储的凭据触发TTS生成，从而可能导致跨源凭据滥用。
