  "details": "A Cross-Site Scripting (XSS) vulnerability has been identified in the Angular Template Compiler. The vulnerability exists because Angular\u2019s internal sanitization schema fails to recognize the `href` and `xlink:href` attributes of SVG `\u003cscript\u003e` elements as a **Resource URL** context.\n\nIn a standard security model, attributes that can load and execute code (like a script\u0027s source) should be strictly validated. However, because the compiler does not classify these specific SVG attributes correctly, it allows attackers to bypass Angular\u0027s built-in security protections.\n\nWhen template binding is used to assign user-controlled data to these attributes for example, `\u003cscript [attr.href]=\"userInput\"\u003e` 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.\n\n### Impact\nWhen successfully exploited, this vulnerability allows for **arbitrary JavaScript execution** within the context of the victim\u0027s browser session. This can lead to:\n- **Session Hijacking:** Stealing session cookies, localStorage data, or authentication tokens.\n- **Data Exfiltration:** Accessing and transmitting sensitive information displayed within the application.\n- **Unauthorized Actions:** Performing state-changing actions (like clicking buttons or submitting forms) on behalf of the authenticated user.\n\n### Attack Preconditions\n\n1. The victim application must explicitly use SVG `\u003cscript\u003e` elements within its templates.\n2. The application must use property or attribute binding (interpolation) for the `href` or `xlink:href` attributes of those SVG scripts.\n3. 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).\n\n### Patches\n- 19.2.18\n- 20.3.16\n- 21.0.7\n- 21.1.0-rc.0\n\n### Workarounds\nUntil the patch is applied, developers should:\n\n- **Avoid Dynamic Bindings**: Do not use Angular template binding (e.g., `[attr.href]`) for SVG `\u003cscript\u003e` elements.\n- **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.\n\n### Resources\n\n- https://github.com/angular/angular/pull/66318",
