Angular is a development platform for building mobile and desktop web applications using TypeScript/JavaScript and other languages. Prior to 22.0.1, 21.2.17, and 20.3.25, an information disclosure vulnerability exists in the @angular/service-worker package of the Angular framework. When the Service Worker fetches assets, it preserves metadata (such as headers) from the original request. However, on cross-origin redirects, the Service Worker fails to strip sensitive headers, violating the Fetch redirect algorithm. This allows a remote attacker to obtain sensitive credentials (e.g., Authorization tokens, Proxy-Authorization credentials, or session cookies) by triggering a cross-origin redirect to an untrusted external origin. This vulnerability is fixed in 22.0.1, 21.2.17, and 20.3.25.

A vulnerability has been identified in SIMATIC PCS 7 V9.1 (All versions < V9.1 SP2 UC05), SIMATIC WinCC Runtime Professional V18 (All versions < V18 Update 5), SIMATIC WinCC Runtime Professional V19 (All versions < V19 Update 2), SIMATIC WinCC V7.4 (All versions < V7.4 SP1 Update 23), SIMATIC WinCC V7.5 (All versions < V7.5 SP2 Update 17), SIMATIC WinCC V8.0 (All versions < V8.0 Update 5). The affected products do not properly handle certain requests to their web application, which may lead to the leak of privileged information. This could allow an unauthenticated remote attacker to retrieve information such as users and passwords.
