Angular 21.x < 21.2.19 Cache Poisoning

high Web App Scanning Plugin ID 115594

Synopsis

Angular 21.x < 21.2.19 Cache Poisoning

Description

According to its self-reported version number, Angular is prior to 20.0.0, 20.x prior to 20.3.27, 21.x prior to 21.2.19 or 22.x prior to 22.0.2. It is, therefore, affected by a cache-key ambiguity vulnerability in the HttpTransferCache of @angular/common. Repeated request parameter values are serialized identically to comma-separated scalar values, allowing an attacker-influenced request to be replayed as the response of a different security-sensitive request during SSR, leading to state poisoning or data leakage. (CVE-2026-68945)

Note that the scanner has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Upgrade to Angular version 21.2.19 or later.
