Session disclosure via stripped request safety options
Published Jun 22, 2026 · Updated Jun 22, 2026
Information disclosure in Google Angular Service Worker allows attackers to read session data from post-logout browser caches. Its asset-request helper reconstructs Request objects without explicit credentials and cache options, restoring browser defaults that attach same-origin credentials or retain private responses. Exposure requires an active service worker, a matching asset group, an authenticated session, and a client fetch that explicitly omits credentials or caching.
