Uncanny Automator <= 6.3.0.2 - Missing Authorization to Authenticated (Subscriber+) Privilege Escalation

The Uncanny Automator – Easy Automation, Integration, Webhooks & Workflow Builder Plugin for WordPress is vulnerable to Privilege Escalation in all versions up to, and including, 6.3.0.2. This is due to add_role() and user_role() functions missing proper capability checks performed through the validate_rest_call() function. This makes it possible for unauthenticated attackers to set the role of arbitrary users to administrator granting full access to the site, though privilege escalation requires an active account on the site so this is considered an authenticated privilege escalation.

Because it turns on account access, WordSec's login security is the relevant layer: role-based two-factor, captcha and brute-force limits raise the cost of getting the account this needs. None of that substitutes for the fix: Uncanny Automator 6.4.0 closes this, and updating the plugin is the step that ends it.
