    Asymmetric Resource Consumption (Amplification)

    Affected versions of this package are vulnerable to Asymmetric Resource Consumption (Amplification) via the router's URL recognition logic (recognize.ts and config_matching.ts) when processing empty-path outlet groups in a request URL (such as x:/(detail:2), ///(detail:2), or x:/()) that have no corresponding route in the route configuration. The four affected code paths - processChildren, processSegmentAgainstRoute, matchSegmentAgainstRoute, and noLeftoversInUrl - allow unmatched zero-segment outlet groups to bypass route validation, enabling an attacker to trigger unbounded recursive processing that exhausts available heap memory and crashes the server process.

    Note: This is only exploitable when worker heaps are sized small enough relative to the request payload and concurrency (e.g., containers or serverless instances configured with 128 MiB-1 GiB).

    How to fix Asymmetric Resource Consumption (Amplification)?

    Upgrade @angular/router to version 20.3.33, 21.2.25, 22.2.1 or higher.
