  "title": "PHP object injection in Gravity Forms",
  "summary": "Gravity Forms through version 3.1.2 can deserialize attacker-controlled data submitted through certain List-type Post Custom Fields. An unauthenticated attacker may inject objects into post metadata when the affected field has a content template enabled; further impact, including code execution, requires additional environment-specific conditions.",
  "mitigation": "Disable public submission or remove content templates from List-type Post Custom Fields until an update is available. Review installed plugins and themes for usable object-deserialization chains, and apply a vendor release that fixes this issue when one is published.",
