Angular is a development platform for building mobile and desktop web applications using TypeScript/JavaScript and other languages. Prior to 21.0.2, 20.3.15, and 19.2.17, A Stored Cross-Site Scripting (XSS) vulnerability has been identified in the Angular Template Compiler. It occurs because the compiler's internal security schema is incomplete, allowing attackers to bypass Angular's built-in security sanitization. Specifically, the schema fails to classify certain URL-holding attributes (e.g., those that could contain javascript: URLs) as requiring strict URL security, enabling the injection of malicious scripts. This vulnerability is fixed in 21.0.2, 20.3.15, and 19.2.17.

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.
