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. This vulnerability is fixed in 4.12.16."

Antes de la 4.12.16, bodyLimit() no aplica de forma fiable maxSize para solicitudes sin un Content-Length utilizable (p. ej., Transfer-Encoding: chunked). Las solicitudes sobredimensionadas pueden alcanzar los manejadores y devolver 200 en lugar de 413. Esta vulnerabilidad está corregida en la 4.12.16."
