description

FrankenPHP worker mode 1.13.2 and 1.13.3 can be terminated by an unauthenticated client using an aborted request under the affected conditions. A successful trigger stops the FrankenPHP process and interrupts in-flight requests for every site it serves; classic mode and releases before 1.13.2 are not affected.

mitigation

Upgrade FrankenPHP to version 1.13.4. If upgrading cannot be completed immediately, use classic mode or downgrade to 1.13.1.

fixed in 1.13.4
