Arbitrary object creation via forged type metadata
Published May 11, 2021 · Updated Aug 3, 2024
Insecure deserialization in Asynkron Wire 1.0.0 and earlier allows remote attackers to instantiate arbitrary object types. A sender-side surrogate supplies metadata for a different receiving type, and the deserializer trusts that metadata when creating the object. Untrusted serialized data must reach a consuming application's deserializer; successful exploitation permits unauthorized object construction that can alter data or interrupt that application.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
