This misinterpretation tricks the application into treating the attacker’s domain as the local origin. Consequently, any relative `HttpClient` requests or `PlatformLocation.hostname` references are redirected to the attacker controlled server, potentially exposing internal APIs or metadata services.\n\n**Affected APIs:**\n- `renderModule`\n- `renderApplication`\n- `CommonEngine` (from `@angular/ssr`)\n\n**Non-Affected APIs:**\n- `AngularAppEngine` (from `@angular/ssr`)\n- `AngularNodeAppEngine` (from `@angular/ssr`)\n\n### Attack Preconditions\n- The server has outbound network access.\n- The application uses Angular SSR via the affected APIs.\n- A pathname is passed as URL to the rendering method  (e.g. using `req.url`).\n- The server-side code performs HTTP requests using `HttpClient` with relative URLs or uses `PlatformLocation.hostname` to build URLs. \n\n\n### Patches\n- 22.0.0-next.8\n- 21.2.9\n- 20.3.19\n- 19.2.21\n\n### Workarounds\nDevelopers should implement a middleware to sanitize the request URL before it reaches Angular. This involves stripping or normalizing leading slashes:\n\n```js\napp.use((req, res, next) => {\n  // Sanitize the URL to ensure it starts with a single forward slash\n  if (req.url.startsWith('//') || req.url.startsWith('/\\\\') || req.url.startsWith('\\\\')) {\n     req.url = '/' + req.url.replace(/^[/\\\\]+/, '');\n  }\n  next();\n});\n\n```\n### References\n-
