CVE-2026-100607— Flowise through 3.1.4 Authentication Bypass via Email-Only SSO

Quick assessment

Affected
FlowiseAI Flowise
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

Flowise 3.1.4 及之前版本仅通过电子邮件来识别单点登录（SSO）和本地密码用户，而未存储身份提供商（provider）或主题标识符（subject identifier）的绑定信息。这使得攻击者可以通过在任何已配置的 SSO 提供商处声称受害者的电子邮件，从而伪装成任何现有用户进行身份验证。攻击者可以通过通过不同的 SSO 提供商或本地密码（而非受害者最初注册时使用的方法）进行身份验证，从而获得对账户的完全访问权限，包括聊天流程（chatflows）、凭证（credentials）和 API 密钥等敏感

Vulnerability Title
Flowise through 3.1.4 Authentication Bypass via Email-Only SSO
Source: CVE Program / CVE List V5
Vulnerability Description
Flowise through 3.1.4 resolves SSO and local-password users solely by email without storing provider or subject identifier bindings, allowing attackers to authenticate as any existing user by claiming their email at any configured SSO provider. Attackers can gain complete account access including chatflows, credentials, and API keys by authenticating through a different SSO provider or local password than the victim's original registration method.
