CVE-2026-54266

Angular’s HttpTransferCache uses a weak 32‑bit DJB2‑like hash to generate TransferState cache keys, enabling hash collisions that let attackers overwrite a victim’s cached SSR responses (state poisoning and potential data leakage) by visiting crafted links. This affects Angular versions prior to ...
