The vulnerability arises from missing authorization checks, a leaked nonce, and inadequate input sanitization, allowing authenticated users with Subscriber role or higher to trigger an AI form generation endpoint that returns raw JavaScript. Since the plugin fails to escape the response, the resulting script is stored and executed whenever any visitor loads the form, giving attackers the ability to run arbitrary code in the context of all site users.", "risk_and_exploitability": "The CVSS score of 6.4 indicates medium severity, while the EPSS score below 1% suggests a very low likelihood of exploitation.
