How to fix?

Upgrade Debian:10 apache2 to version 2.4.38-3+deb10u7 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream apache2 package and not the apache2 package as distributed by Debian. See How to fix? for Debian:10 relevant fixed versions and status.

A carefully crafted request body can cause a buffer overflow in the mod_lua multipart parser (r:parsebody() called from Lua scripts). The Apache httpd team is not aware of an exploit for the vulnerabilty though it might be possible to craft one. This issue affects Apache HTTP Server 2.4.51 and earlier.
