REST API unable to make requests with slash (/) in SKU

[xfolder]

Preconditions

1. Tested in CE 2.3

Steps to reproduce

Fresh install
Create product (of any type) with SKU containing /, e.g. "0RJ9548SN-212/W0-54"

searching for the product with
GET : /rest/v1/products?searchCriteria[filter_groups][0][filters][0][field]=sku&searchCriteria[filter_groups][0][filters][0][value]=0RJ9548SN-212%2FW0-54
returns results as expected

but when getting the stockItems with the following
GET : /rest/V1/stockItems/0RJ9548SN-212%2FW0-54
result 404 status - BUT the actual data is returned?

when trying to update the stockItem
PUT : /rest/V1/products/0RJ9548SN-212%2FW0-54/stockItems/100
result : 404 status - message=Request does not match any route.

Expected result

expect
/rest/V1/stockItems/[sku containing / to also work]
/rest/V1/products/[sku containing / to also work]/stockItems/[stockItemID]

both to work in the same manner as sku without '/'

Actual result

GET : /rest/V1/stockItems/0RJ9548SN-212%2FW0-54
result 404 status - BUT the actual data is returned?

PUT : /rest/V1/products/0RJ9548SN-212%2FW0-54/stockItems/100
result : 404 status - message=Request does not match any route.

This is not a Magento 2 bug, but an apache2 one.
By default apache should not allow encoded slashes in url without use of "AllowEncodedSlashes", (for security reasons) but sometimes it does.
If You really need to use "/" in SKUs then configure apache with "AllowEncodedSlashes On" directive. (not recommended)

Instead of looking for workaround for this case, Magento should not allow for usage of slash (%2F) and backslash (%5C) in SKU.

[ihor-sviziev]

@henryk-zaborowski

If You really need to use "/" in SKUs then configure apache with "AllowEncodedSlashes On" directive. (not recommended)

I would say it's better to use

AllowEncodedSlashes NoDecode

With the default value, Off, such URLs are refused with a 404 (Not found) error.
With the value On, such URLs are accepted, and encoded slashes are decoded like all other encoded characters.
With the value NoDecode, such URLs are accepted, but encoded slashes are not decoded but left in their encoded state.

More details: https://httpd.apache.org/docs/2.4/mod/core.html#allowencodedslashes
