CVE-2024-49063

Local code execution via unsafe deserialization

Published Dec 10, 2024 · Updated Jun 9, 2026

Deserialization of untrusted data in Microsoft Muzic before 196.0 allows local users to execute arbitrary code through crafted input. Microsoft identifies CWE-502 but has not disclosed the affected component, data format, or deserialization call that consumes the input. Exploitation requires local access but no prior application privileges or user interaction, and successful execution grants control in the Muzic process context.
