  "title": "Unsafe deserialization callback invocation in seroval",
  "summary": "Seroval versions before 1.6.8 can invoke an application plugin-provided value while processing crafted serialized data. An attacker needs control of Seroval input and a plugin that exposes a callable value or an object with an `on` method; the resulting impact depends on the plugin's behavior.",
  "mitigation": "Upgrade seroval to version 1.6.8 or later. Until upgraded, do not deserialize untrusted Seroval data and review plugins that expose callable values or `on` methods.",
