  "summary": "Ninja Forms for WordPress through version 3.15.5 is affected by stored cross-site scripting.

  "mitigation": "Disable the affected Ninja Forms plugin until the vendor provides and you can deploy a fixed release. Limit access to affected WordPress sites and review potentially injected form content before re-enabling it.",
