## Technical details

The vulnerability exists in the deserialization mechanism that processes untrusted serialized .NET objects without proper validation. An unauthenticated remote attacker can craft malicious serialized payloads and send them to the application, achieving arbitrary code execution in the server context with no authentication required. Patches released after April 16, 2026 address this issue.
