I ran a security scan via official Magento tool(free) and got the following
Presently my site is running on Magento 2.3 vis a vis the latest version 2.3.1 , and I am running it on a droplet in Digital Ocean
The first error is API ACL, which is actually a patch released in 2016 and I did not have this error till 17th April , more ever clicking the link redirects me to the magento 2.0 release devdocs( mine is magento 2.3)
I do not understand the second point although I feel it may be a minor issue. If you would be kind enough to elaborate on that.
The third point looks relatively simple and I will do it by googling I think.
I request you for help regarding this if you can, I will be highly grateful.
Thanks in advance.
