Vulnerability Title
Cross-Tenant API Key Reuse and Billing Fraud in Langflow Voice Mode Subsystem
Source: CVE Program / CVE List V5
Vulnerability Description
IBM Langflow OSS 1.0.0 through 1.10.0 voice mode contains improper shared-state handling that allows reuse of API clients across tenant boundaries. An authenticated attacker can manipulate cache state to cause requests from other users to be processed using incorrect upstream API credentials, leading to cross-tenant billing and accountability misattribution.

Vulnerability Title
IBM Langflow OSS 授权问题漏洞
Source: CNNVD (China National Vulnerability Database)
Vulnerability Description
IBM Langflow OSS是美国IBM公司的一个开源的低代码可视化AI工作流构建工具，它让开发者能通过拖拽组件的方式快速搭建、部署和迭代AI智能体与RAG应用，同时支持用Python进行深度定制以集成企业系统。 IBM Langflow OSS 1.0.0版本至1.10.0版本存在授权问题漏洞，该漏洞源于语音模式中存在不当的共享状态处理问题，可能导致经过身份验证的攻击者操纵缓存状态，使其他用户的请求使用错误的上游API凭据进行处理，从而造成跨租户计费和责任归属错误。
