NewCVE-2026-54266 (opens in a new tab)How to fix?
Upgrade @angular/common to version 20.3.25, 21.2.17, 22.0.1 or higher.
Overview
Affected versions of this package are vulnerable to Use of Weak Hash due to the use of a weak 32-bit hash in the HttpTransferCache. When a victim visits a crafted link containing the colliding parameter, the SSR process executes both the search request and the profile request. Due to the hash collision, the search response overwrites the profile response in the TransferState cache.
Workaround
This vulnerability can be mitigated by configuring HTTP requests to skip transfer caching for sensitive endpoints or by disabling the HTTP transfer cache globally in the application bootstrap configuration.
