KEV: No
Impact: Unauthorized form generation and AI usage consumption
Action: Update Plugin
AI Analysis

Impact

The plugin has a missing capability check on the run_callback function, allowing any user, even unauthenticated visitors, to call the AI form generation endpoint. This permits the unauthorized creation of forms, causing the site to consume AI usage limits without permission. The vulnerability is a classic missing authorization flaw (CWE‑862) that enables unwanted data modification in the form builder system.

Affected Systems

JetFormBuilder plugins for WordPress released by Jet Monsters with versions up to and including 3.5.3 are affected, as the missing check exists in all those releases.

Risk and Exploitability

The CVSS score of 5.3 indicates moderate severity, while an EPSS score of less than 1 % shows a very low exploitation probability. The vulnerability is not listed in CISA's KEV catalog. Attackers would likely leverage unauthenticated HTTP requests to the AI form generation endpoint to create forms, draining the site's AI usage limits and potentially leading to denial of paid AI features, but the impact is limited to resource consumption rather than system compromise.

Remediation

No vendor fix or workaround currently provided.

OpenCVE Recommended Actions

  • Upgrade JetFormBuilder to version 3.5.4 or later to remove the missing authorization check.
  • If an upgrade is not yet available, disable the AI form generation endpoint by removing or blocking its route in the plugin’s configuration.
  • Monitor the site’s AI usage statistics and enforce rate limits to detect and mitigate unauthorized form creation attempts.
