Angular is a development platform for building mobile and desktop web applications using TypeScript/JavaScript and other languages. Prior to versions 19.2.18, 20.3.16, 21.0.7, and 21.1.0-rc.0, a cross-site scripting (XSS) vulnerability has been identified in the Angular Template Compiler. The vulnerability exists because Angular’s internal sanitization schema fails to recognize the href and xlink:href attributes of SVG <script> elements as a Resource URL context. This issue has been patched in versions 19.2.18, 20.3.16, 21.0.7, and 21.1.0-rc.0.

- GHSA-jrmj-c5cx-3cw6Angular has XSS Vulnerability via Unsanitized SVG Script Attributes2026-01-09ghsa · osvUS
A Cross-Site Scripting (XSS) vulnerability has been identified in the Angular Template Compiler. The vulnerability exists because Angular’s internal sanitization schema fails to recognize the `href` and `xlink:href` attributes of SVG `<script>` elements as a **Resource URL** context. In a standard security model, attributes that can load and execute code (like a script's source) should be strictly validated. However, because the compiler does not classify these specific SVG attributes correctly, it allows attackers to bypass Angular's built-in security protections. When template binding is used to assign user-controlled data to these attributes for example, `<script [attr.href]="userInput">` the compiler treats the value as a standard string or a non-sensitive URL rather than a resource link. This enables an attacker to provide a malicious payload, such as a `data:text/javascript` URI or a link to an external malicious script. ### Impact When successfully exploited, this vulnerability allows for **arbitrary JavaScript execution** within the context of the victim's browser session. This can lead to: - **Session Hijacking:** Stealing session cookies, localStorage data, or authentication tokens. - **Data Exfiltration:** Accessing and transmitting sensitive information displayed within the application. - **Unauthorized Actions:** Performing state-changing actions (like clicking buttons or submitting forms) on behalf of the authenticated user. ### Attack Preconditions 1. The victim application must explicitly use SVG `<script>` elements within its templates. 2. The application must use property or attribute binding (interpolation) for the `href` or `xlink:href` attributes of those SVG scripts. 3. The data bound to these attributes must be derived from an untrusted source (e.g., URL parameters, user-submitted database entries, or unsanitized API responses). ### Patches - 19.2.18 - 20.3.16 - 21.0.7 - 21.1.0-rc.0 ### Workarounds Until the patch is applied, developers should: - **Avoid Dynamic Bindings**: Do not use Angular template binding (e.g., `[attr.href]`) for SVG `<script>` elements. - **Input Validation**: If dynamic values must be used, strictly validate the input against a strict allowlist of trusted URLs on the server side or before it reaches the template. ### Resources - https://github.com/angular/angular/pull/66318
