Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

Angular是Angular组织开源的一个开发平台。用于使用 Typescript / JavaScript 和其他语言构建移动和桌面 Web 应用程序。 Angular 20.3.27之前版本、21.2.19之前版本和22.0.2之前版本存在输入验证错误漏洞，该漏洞源于HttpTransferCache对重复请求参数进行逗号连接，导致语义不同的HttpClient请求使用相同的传输缓存键并重用错误的后端响应。

Vulnerability Title
Angular: Cache-Key Ambiguity in HttpTransferCache Leading to Cross-Request Response Reuse and State Poisoning
Source: CVE Program / CVE List V5
Vulnerability Description
Angular is a development platform for building mobile and desktop web applications using TypeScript/JavaScript and other languages. Prior to 20.3.27, 21.2.19, and 22.0.2, HttpTransferCache comma-joins repeated request parameters, allowing semantically distinct HttpClient requests to use the same transfer-cache key and reuse a wrong backend response. This issue is fixed in versions 20.3.27, 21.2.19, and 22.0.2.
