@angular/router 3.2.0 before 20.3.33, 21.2.25 and 22.2.1: route recognition does not reject unconfigured empty-path auxiliary outlet segments, so with SSR a URL with many such outlets makes the router re-evaluate the configuration per outlet and exhaust the Node.js heap or CPU (denial of service). Lines 19 and older are not fixed. (GHSA-62vg-58rm-qff7)
