Description

Angular is a development platform for building mobile and desktop web applications using TypeScript/JavaScript and other languages. Prior to 20.3.27, 21.2.19, and 22.0.2, HttpTransferCache comma-joins repeated request parameters, allowing semantically distinct HttpClient requests to use the same transfer-cache key and reuse a wrong backend response. This issue is fixed in versions 20.3.27, 21.2.19, and 22.0.2.

Affected products

• angular: through 19.2.25; from 20.0.0 before 20.3.27; from 21.0.0 before 21.2.19; from 22.0.0 before 22.0.2 — fixed in 20.3.27, 21.2.19, 22.0.2

How to fix

Upgrade to a fixed version: angular 20.3.27, 21.2.19, 22.0.2. Check the vendor advisory for mitigations.
