The AutomatorWP Pro plugin for WordPress' webhook addon is vulnerable to authorization bypass in all versions up to, and including, 1.4.4. This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for unauthenticated attackers to reset the password of any WordPress account, including administrators, resulting in full account takeover. This is only exploitable when an administrator has configured an automation pairing a Receive Webhook trigger — with an 'Is the user ID' field — to an Update-User action whose User ID field is left blank and whose Password field is mapped to the webhook password tag, which is a documented, supported plugin configuration.
