In simple words, open_basedir protection forbids your PHP scripts to access file system beyond the specified path i.e.
open_basedir "/home/domain.com/"
If this path is specified for open_basdir, your PHP code cannot access file system beyond /home/domain.com/
Which basically helps in case a single site on the server is hacked.
How to enable open_basedir Protection
For open_basedir you need CyberPanel version 1.6.4 stable and OpenLiteSpeed version 1.4.32 stable.
While creating a site you can opt to enable open_basedir protection, if not opted this is disabled by default.
Enable/Disable open_basedir Protection
In case you forgot to enable open_basedir protection while creating a site you can do so later as well.
Open website launcher:
Once launcher is opened, scroll down to find open_basedir under Files.
From a drop-down, you can either select Enable or Disable and apply changes. Similarly, you can also control open_basedir for Child Domains through child domain launcher.
Edit open_basedir paths
To edit the paths, modify the phpIniOverride section in the website’s vHost Conf.
You cannot add multple open_basedir overrides, so to edit the paths that are accessible, simply add a : after each path.
