description

Angular applications using @angular/router for on-demand Node.js server-side rendering may be affected when their routes include empty paths or named outlets. An unauthenticated attacker can send a malformed route URL that consumes worker memory or CPU, potentially terminating SSR processes; browser-only applications and build-time prerendering are not affected.

mitigation

Upgrade @angular/router to 22.2.1, 21.2.25, or 20.3.33, as appropriate for the maintained Angular release line. Until upgraded, reject auxiliary-outlet URL syntax at the edge or before the SSR handler, and apply a full request-target length limit; releases before 20 have no upstream patch.

fixed in 22.2.1, 21.2.25, 20.3.33

outcome

Mechanism verified: the exploit fired on the vulnerable build and stayed silent on the patched one, but the server it ran against was ours, so no check ships for it.
