Angular 19.x < 19.2.17 Cross-Site Scripting

high Web App Scanning Plugin ID 115631

Synopsis

Angular 19.x < 19.2.17 Cross-Site Scripting

Description

According to its self-reported version number, Angular is prior to 19.0.0, 19.x prior to 19.2.17, 20.x prior to 20.3.15 or 21.x prior to 21.0.2. It is, therefore, affected by a stored Cross-Site Scripting (XSS) vulnerability in the Angular template compiler. The security schema does not classify some SVG and MathML URL-holding attributes as requiring URL sanitization, and the attributeName attribute of SVG animation elements is not validated, allowing javascript: URLs to bypass sanitization. (CVE-2025-66412)

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 19.2.17 or later.
