Thank you so much for your advice.In the current configuration, SELinux allow write to whom?Can you tell me in your opinion which directories of WordPress must have "httpd_sys_rw_content_t" label and which one "httpd_sys_r_content_t" label?

1. Well just turning on your computer can lead to it beeing hacked... Just remember SELinux is a part of the kernel with some policies defined. You are the one making the rules but by default everything is denied. (fyi would recommend you going through this https://people.redhat.com/duffy/selinux/selinux-coloring-book_A4-Stapled.pdf it is really well explained). well httpd_sys_r_content_r allow only read only access weither httpd_sys_rw_content_t allows also write. What is dangerous is the write one beeing defined everywhere (like in any systems). You can mix both, on the files that wordpress should write:httpd_sys_rw_content_t and the rest httpd_sys_r_content_t.
2. this command is setting a boolean to on that allows any programs under the httpd context to communicate over the internet (yes SELinux controls everything).
So as a resume, nothing is either white or black but rather a mix of the 2.
And btw if you are really preoccupied about security as a whole just throw away wordpress (or run it as a static website (for example with gaby).

Hello, I'm using CentOS 8 as a web server that hosting a WordPress website. I have two questions. 1- I defined SELinux for WordPress directory as below:
# ls -lZ /var/www/ drwxrwxr-x. 7 apache apache unconfined_u:object_r:httpd_sys_rw_content_t:s0 4096 Sep 19 23:37 wp
I created an account for a remote developer that working on WordPress. On some websites, I saw that the OK permission for wp directory is "httpd_sys_r_content_t" and not "httpd_sys_rw_content_t" and someone recommended to back permission via below command:
# restorecon -rv /var/www/wp
Is it true? Is "httpd_sys_rw_content_t" a dangerous permission and can lead to hacking?
2- WordPress can't update and showed me "cURL Error (7): couldn't connect to host" error. I did below command to solve it:
# setsebool -P httpd_can_network_connect on
Can this command make Apache insecure and must I turn it to "off" ?
Thank you.
