CVE-ID: N/A

CWE-ID: CWE-264 - Permissions, Privileges, and Access Controls

Description

The vulnerability allows a remote attacker to escalate privileges on the system.

The vulnerability exists due to the "companion_disable_popup" function only checks the nonce and will pass two user input, $_POST['value'] and $_POST['option'], to the "update_option" function. A remote authenticated attacker can copy the nonce, use it to send an AJAX request and modify WordPress core options in the "wp_options" table.

Mitigation

Install updates from vendor's website.
