2399	$request_body incomplete if the request body contains NUL/control characters	AD7six@…		"If a post body contains `\x00` (or maybe other control characters) the variable `$request_body` is incomplete.

Two examples:
* a post request with the content `BEFORE_NULL\x00AFTER_NULL` - the variable `$request_body` contains only `BEFORE_NULL`.
* a post request with the content `SOME_PREFIX\x00... some more content \x01 ...MESSAGE CONTINUES HERE` - the variable `$request_body` contains only `SOME PREFIX MESSAGE CONTINUES HERE`

I'm not sure of the exact mechanics of what's happening here, but I've created a minimal, reproducible example here: https://github.com/AD7six/nginx-partial-request-body-repro based on the current `nginx:latest` docker image.

Am happy to provide more information if necessary or to chat about this via the community nginx slack https://nginxcommunity.slack.com/archives/C02T18NMZU4/p1665412094085809."	defect	closed	minor		nginx-core	1.23.x	invalid	request_body	AD7six@…	Linux e7fd02de8b5b 5.10.104-linuxkit #1 SMP Thu Mar 17 17:08:06 UTC 2022 x86_64 GNU/Linux	"nginx version: nginx/1.23.1
