flight.allow_method_overrideso setting it tofalseactually disablesX-HTTP-Method-Overrideand_methodmethod spoofing (GHSA-vr9m-jx6f-hhj6). The mitigation introduced for CVE-2026-42551 was applied afterRequestwas constructed, so the opt-out never took effect on routing.
Upgrade note: If you set Flight::set('flight.allow_method_override', false) on 3.18.1–3.19.0, upgrade to 3.19.1 for that setting to work. The default remains true for backwards compatibility; disabling override is still recommended when you do not need HTML form method spoofing.
