CVE-2026-93710

NVD: Dancer2 versions from 2.0.0 before 2.2.0 for Perl dispatch a route that a dying hook refused when the exception handler halts the response in compile_hooks. NVD: A hook that dies fires core.app.hook_exception, then calls cleanup unless the failing hook is the exception handler. NVD: A handler that halts does not stop that cleanup, which discards the request, response and session the dispatcher has yet to read, so the refused route runs.
