Use of Weak Hash

CVE-2026-54266

High
8.8/10

Summary

Angular's `HttpTransferCache` caches HTTP requests made during Server-Side Rendering (SSR) so that they can be reused during client-side hydration. This avoids repeating the same HTTP requests on the client. The cached responses are stored in `TransferState` using a cache key generated by hashing request properties (method, response type, mapped URL, serialized body, and sorted query parameters). Issue has been patched in 22.0.1, 21.2.17, 20.3.25.

CWE-328 - Use of Weak Hash

The product uses an algorithm that produces a digest (output value) that does not meet security expectations for a hash function that allows an adversary to reasonably determine the original input (preimage attack), find another input that can produce the same hash (2nd preimage attack), or find multiple inputs that evaluate to the same hash (birthday attack).
