Angular 21.x < 21.2.23 Denial of Service

high Web App Scanning Plugin ID 115574

Synopsis

Angular 21.x < 21.2.23 Denial of Service

Description

According to its self-reported version number, Angular is prior to 20.0.0, 20.x prior to 20.3.31, 21.x prior to 21.2.23 or 22.x prior to 22.1.6. It is, therefore, affected by a denial of service vulnerability in the DOM emulation parser (domino) of @angular/platform-server. Processing untrusted input containing an incomplete DOCTYPE declaration ending with whitespace before EOF causes an infinite loop, freezing the Node.js server process. (CVE-2026-101895)

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 21.2.23 or later.
