Summary

In Angular prior to versions 22.0.1, 21.2.17, and 20.3.25, a vulnerability in the @angular/compiler package allows bypassing DOM property sanitization through two-way property bindings. An attacker who controls the value of a sensitive property can bypass Angular's built-in sanitization, leading to client-side Cross-Site Scripting (XSS).

Risk Assessment

The risk is potential client-side Cross-Site Scripting (XSS) attacks, which could lead to session data theft, account takeover, or unauthorized content modification.

Recommendation

Immediately update Angular to version 22.0.1, 21.2.17, or 20.3.25 depending on your branch. After updating, review your code for two-way bindings on sensitive DOM properties.

Original NVD description (English source)

Angular is a development platform for building mobile and desktop web applications using TypeScript/JavaScript and other languages. Prior to 22.0.1, 21.2.17, and 20.3.25, an issue in the @angular/compiler package allows bypassing DOM property sanitization through the use of two-way property bindings. Specifically, when a native DOM property that requires sanitization (such as innerHTML, srcdoc, src, href, data, or sandbox) is bound using the two-way binding syntax (e.g., [(innerHTML)]="value" or bindon-innerHTML="value"), the Angular template compiler failed to apply the appropriate schema-derived sanitizer resolution to the TwoWayProperty operation. As a result, native two-way DOM bindings were emitted without the required sanitizer function, whereas equivalent one-way bindings would be properly sanitized. This flaw enables an attacker who can control the value of a two-way bound sensitive property to bypass Angular's built-in sanitization logic, potentially leading to client-side Cross-Site Scripting (XSS). This vulnerability is fixed in 22.0.1, 21.2.17, and 20.3.25.
