It occurs when the application uses a security-sensitive attribute (for example href on an anchor tag) together with Angular's ability to internationalize attributes. Enabling internationalization for the sensitive attribute by adding `i18n-<attribute>` name bypasses Angular's built-in sanitization mechanism, which when combined with a data binding to untrusted user-generated data can allow an attacker to inject a malicious script. \n\nThe following example illustrates the issue:\n```html\n<a href=\"{{maliciousUrl}}\" i18n-href>Click me</a>\n```\n\nThe following attributes have been confirmed to be vulnerable:\n- `action`\n- `background`\n- `cite`\n- `codebase`\n- `data`\n- `formaction`\n- `href`\n- `itemtype`\n- `longdesc`\n- `poster`\n- `src`\n- `xlink:href`\n\n### Impact\nWhen exploited, this vulnerability allows an attacker to execute arbitrary code within the context of the vulnerable application's domain. This enables:\n- Session Hijacking: Stealing session cookies and authentication tokens.\n- Data Exfiltration: Capturing and transmitting sensitive user data.\n- Unauthorized Actions: Performing actions on behalf of the user.\n\n### Attack Preconditions\n1. The application must use a vulnerable version of Angular.\n2. The application must bind unsanitized user input to one of the attributes mentioned above.\n3. The bound value must be marked for internationalization via the presence of a `i18n-<name>` attribute on the same element.\n\n### Patches\n- 22.0.0-next.3\n- 21.2.4\n- 20.3.18\n- 19.2.20\n\n### Workarounds\nThe primary workaround is to ensure that any data bound to the vulnerable attributes is **never sourced from untrusted user input** (e.g., database, API response, URL parameters) until the patch is applied, or when it is, it shouldn't be marked for internationalization.\n\nAlternatively, users can explicitly sanitize their attributes by passing them through Angular's `DomSanitizer`:\n```ts\nimport {Component, inject, SecurityContext} from '@angular/core';\nimport {DomSanitizer} from '@angular/platform-browser';\n\n@Component({\n template: `\n <form action=\"{{url}}\" i18n-action>\n <button>Submit</button>\n </form>\n `,\n})\nexport class App {\n url: string;\n\n constructor() {\n const dangerousUrl = 'javascript:alert(1)';\n const sanitizer = inject(DomSanitizer);\n this.url = sanitizer.sanitize(SecurityContext.URL, dangerousUrl) || '';\n }\n}\n```\n\n### References\n- [Fix 1](https://github.com/angular/angular/pull/67541) \n- [Fix

"vulnerability_id": "VCID-ms76-c5dn-23hx", "summary": "Angular has XSS Vulnerability via Unsanitized SVG Script Attributes\nA 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.\n\nIn 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.\n\nWhen 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.\n\n### Impact\nWhen successfully exploited, this vulnerability allows for **arbitrary JavaScript execution** within the context of the victim's 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 `<script>` 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 `<script>` 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", "references": [ { "reference_url": "https://access.redhat.com/hydra/rest/securitydata/cve/CVE-2026-22610.json",

Attributes\nA **Stored Cross-Site Scripting ([XSS](https://angular.dev/best-practices/security#preventing-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](https://developer.mozilla.org/en-US/Web/URI/Reference/Schemes/javascript)) as requiring strict URL security, enabling the injection of malicious scripts.\n\nAdditionally, a related vulnerability exists involving SVG animation elements (`<animate>`, `<set>`, `<animateMotion>`, `<animateTransform>`). The `attributeName` attribute on these elements was not properly validated, allowing attackers to dynamically target security-sensitive attributes like `href` or `xlink:href` on other elements. By binding `attributeName` to \"href\" and providing a `javascript:` URL in the `values` or `to` attribute, an attacker could bypass sanitization and execute arbitrary code.\n\nAttributes confirmed to be vulnerable include:\n* SVG-related attributes: (e.g., `xlink:href`), and various MathML attributes (e.g., `math|href`, `annotation|href`).\n* SVG animation `attributeName` attribute when bound to \"href\" or \"xlink:href\".\n\nWhen template binding is used to assign untrusted, user-controlled data to these attributes (e.g., `[attr.xlink:href]=\"maliciousURL\"` or `<animate [attributeName]=\"'href'\" [values]=\"maliciousURL\">`), the compiler incorrectly falls back to a non-sanitizing context or fails to block the dangerous attribute assignment. This allows an attacker to inject a `javascript:URL` payload. Upon user interaction (like a click) on the element, or automatically in the case of animations, the malicious JavaScript executes in the context of the application's origin.", "references": [ {
