  "title": "Unexpected thenable invocation in Seroval deserialization",
  "summary": "Seroval 0.12.0 through 1.6.1 is affected when applications use plugin-capable releases and deserialize untrusted data with fromJSON. An attacker who can supply the serialized JSON may cause an application-controlled callable associated with a thenable value to be invoked during Promise processing.",
