Summary
The Hustle WordPress plugin before version 7.8.14.2 does not prevent shortcodes in submitted form values from being executed when it substitutes those values into the message it returns after submission, because the guard it applies can be defeated by nesting, allowing unauthenticated users to run any shortcode registered on the site.
Risk Assessment
An attacker can execute arbitrary shortcodes, potentially leading to site takeover, data theft, or malware distribution. It may also compromise content integrity and user trust.
Recommendation
Update the Hustle plugin to version 7.8.14.2 or later. Also check other plugins for similar shortcode injection vulnerabilities.
