{"id":"CVE-2026-111754","published":"2026-11-03T21:16:58.203","lastModified":"2026-11-03T22:17:44.523","description":"Angular is a development platform for building mobile and desktop web applications using TypeScript/JavaScript and other languages. Prior to 20.3.33, 21.2.25, and 22.2.1, ServerPlatformLocation in Angular server-side rendering checks for protocol-relative URLs before WHATWG URL normalization. A request path containing a popping dot segment followed by multiple slashes can bypass the raw resolveUrl check and normalize to a pathname beginning with two slashes. When Angular SSR detects a mismatch with the router's final location, it can place that pathname in an HTTP Location header, causing a browser to navigate to an attacker-controlled origin. Affected applications use @angular/platform-server and @angular/ssr and either expose compatible parameter or child route shapes or pass user-controlled navigation targets through infrastructure that preserves the relevant dot segments or semicolons. Pure client-side SPAs are not affected. This issue is fixed in versions 20.3.33, 21.2.25, and 22.2.1.","cvssScore":null,"cvssSeverity":null,"cvssVector":null,"cwes":["CWE-601"],"vendors":[],"products":[],"references":[{"url":"https://github.com/angular/angular/commit/450af9c813c7660b9bd91e5635f705ee3ed7b32a","tags":[]},{"url":"https://github.com/angular/angular/commit/83944fc8c50e86be90e8ec4184cd15002b5af262","tags":[]},{"url":"https://github.com/angular/angular/commit/928dcfd2582152655b5559509d057bf6a5a19521","tags":[]},{"url":"https://github.com/angular/angular/issues/71076","tags":[]},{"url":"https://github.com/angular/angular/pull/71077","tags":[]},{"url":"https://github.com/angular/angular/pull/71078","tags":[]},{"url":"https://github.com/angular/angular/pull/71079","tags":[]},{"url":"https://github.com/angular/angular/releases/tag/v20.3.33","tags":[]},{"url":"https://github.com/angular/angular/releases/tag/v21.2.25","tags":[]},{"url":"https://github.com/angular/angular/releases/tag/v22.2.1","tags":[]},{"url":"https://github.com/angular/angular/security/advisories/GHSA-w739-gvwx-grc3","tags":[]}],"exploitRefs":[{"url":"https://github.com/angular/angular/commit/450af9c813c7660b9bd91e5635f705ee3ed7b32a","tags":[]},{"url":"https://github.com/angular/angular/commit/83944fc8c50e86be90e8ec4184cd15002b5af262","tags":[]},{"url":"https://github.com/angular/angular/commit/928dcfd2582152655b5559509d057bf6a5a19521","tags":[]},{"url":"https://github.com/angular/angular/issues/71076","tags":[]},{"url":"https://github.com/angular/angular/pull/71077","tags":[]},{"url":"https://github.com/angular/angular/pull/71078","tags":[]},{"url":"https://github.com/angular/angular/pull/71079","tags":[]},{"url":"https://github.com/angular/angular/releases/tag/v20.3.33","tags":[]},{"url":"https://github.com/angular/angular/releases/tag/v21.2.25","tags":[]},{"url":"https://github.com/angular/angular/releases/tag/v22.2.1","tags":[]},{"url":"https://github.com/angular/angular/security/advisories/GHSA-w739-gvwx-grc3","tags":[]}],"hasPoc":true,"ai":null}
