@angular/router: Denial of Service via Unmatched Empty-Path Outlet Route Matching in Server-Side Rendering (SSR)

影響: npm:@angular/router >= 22.0.0, < 22.2.1 → 22.2.1, npm:@angular/router >= 21.0.0, < 21.2.25 → 21.2.25, npm:@angular/router >= 20.0.0, < 20.3.33 → 20.3.33, npm:@angular/router <= 19.2.25 A denial of service (DoS) vulnerability was identified in @angular/router when Server-Side Rendering (SSR) is enabled on Node.js (V8). During route recognition, @angular/router fails to validate whether an auxiliary outlet segment in the URL matches a route configured for that specific outlet name. Because unconfigured empty-path outlet groups (such as a:/(), x:/(...), or ///(...)) are not rejected during matching, the router repeatedly re-evaluates the route configuration against each arbitrar…
