AI-suggested
To mitigate CVE-2024-8253, organizations should immediately verify if their WordPress installations use the Post Grid and Gutenberg Blocks plugin versions 2.2.87 to 2.2.90 and upgrade to a patched version once available. Until a patch is released, administrators should restrict plugin access to trusted users only and consider disabling or removing the plugin if feasible. Implement strict user role and capability management to limit subscriber-level users from accessing plugin features that update user meta. Additionally, monitor user meta changes for suspicious activity and audit logs for unauthorized privilege escalations. Applying Web Application Firewall (WAF) rules to detect and block abnormal requests targeting user meta updates can provide temporary protection. Regular backups and incident response plans should be in place to recover from potential compromises. Engage with the plugin vendor or security community for updates on patches or workarounds.
Description
The Post Grid and Gutenberg Blocks plugin for WordPress is vulnerable to privilege escalation in all versions 2.2.87 to 2.2.90. This is due to the plugin not properly restricting what user meta values can be updated and ensuring a form is active. This makes it possible for authenticated attackers, with subscriber-level access and above, to update their user meta to become an administrator.
