  "summary": "The WordPress User Registration plugin is affected through version 5.2.8 when processing checkbox field values.

  "mitigation": "Update the plugin to a vendor-confirmed release newer than 5.2.8. Until an update is deployed, disable public registration through the plugin or block its unauthenticated form-submission endpoint, recognizing that this may interrupt registrations.",
