Until an official fix is available, restrict Contributor-level access to trusted users only. Monitor for plugin updates from the vendor and apply them promptly once released. Avoid enabling new user registrations unless necessary and review user roles regularly to detect unauthorized privilege escalations.
Description
The Post Grid Gutenberg Blocks and WordPress Blog Plugin – PostX plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the 'postx_presets_callback' function in all versions up to, and including, 4.1.2. This makes it possible for authenticated attackers, with Contributor-level access and above, to change arbitrary options on affected sites. This can be used to enable new user registration and set the default role for new users to Administrator.
