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.
