Description
The vulnerability allows a remote attacker to gain unauthorized access to otherwise restricted functionality.
The vulnerability exists due to improper access restrictions in the first-time install wizard in the "wp-security-audit-log/classes/Views/SetupWizard.php" script when the plugin registers the "setup_page" method via the "admin_init" hook. A remote attacker can run the wizard by accessing "wp-admin/admin-post.php?page=wsal-setup" and change every option of the plugin, leading to privilege escalation, sensitive data exposure and insecure deserialization.
Note: To exploit this vulnerability, the wizard must not have been completed, otherwise it won’t work.
Remediation
Install updates from vendor's website.
