CVE-2026-44456 Hono: bodyLimit() can be bypassed for chunked / unknown-length requests

Hono is a Web application framework that provides support for any JavaScript runtime. Prior to 4.12.16, bodyLimit does not reliably enforce maxSize for requests without a usable Content-Length e.g. Transfer-Encoding: chunked. Oversized requests can reach handlers and return 200 instead of 413. Th...
