Why it matters

This matters because the affected product may be exposed on public websites. A vulnerable plugin can create a direct path to site compromise, malicious code deployment, or data theft.

Recommended admin actions

• Prioritize validation immediately due to critical CVSS severity.
• Check whether the affected WordPress plugin or theme is installed.
• Update, disable, or remove the affected component if present.
• Compare installed versions against the affected version range in the advisory.
• Treat internet-facing systems as higher priority.

Technical summary

The ACPT (Premium) plugin for WordPress is vulnerable to Privilege Escalation in all versions up to, and including, 2.0.66. This is due to missing authorization in the `submit()` function, which allows unauthenticated form submissions to control the target user ID before calling `wp_update_user()`. This makes it possible for unauthenticated attackers to overwrite any WordPress user's email address and password, including an administrator's, and take over the account. Successful exploitation requires a public ACPT user form that permits anonymous submissions.
