  "summary": "smub WPForms AI Form Builder versions through 2.0.2 are affected by reflected cross-site scripting. An unauthenticated attacker may cause browser-side script execution when a user interacts with attacker-controlled content and an administrator has placed the page-title smart tag in an HTML attribute within a form confirmation.",
  "mitigation": "Remove the page-title smart tag from HTML attributes in form confirmation messages and review existing forms for that pattern. Upgrade to a release newer than 2.0.2 when the vendor provides one; the evidence does not identify the first fixed version.",
