Message:

General: Remove any usage of wp_reset_vars().

The way wp_reset_vars() sets global variables based on $_POST and $_GET values makes code hard to understand and maintain. It also makes it easy to forget to sanitize input.

This change removes the few places where wp_reset_vars() is used in the admin to explicitly use $_REQUEST and sanitize any input.

Props swissspidy, audrasjb, davideferre, killua99, weijland, voldemortensen.
Fixes #38073.
