Summary
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. A flaw was found in Angular's HttpTransferCache component.
This component, used for caching HTTP requests during server-side rendering, incorrectly generates cache keys when repeated request parameters are present, causing semantically different requests to share the same cache key.
This cache-key ambiguity can lead to cross-request response reuse and state poisoning, where a security-sensitive request might receive an incorrect or attacker-influenced cached response. This could result in an application displaying wrong information or operating with corrupted data, potentially leading to information disclosure.
