CVE-2025-42999 is an insecure deserialization vulnerability in the SAP NetWeaver Visual Composer Metadata Uploader. A privileged, authenticated user can upload untrusted or malicious serialized content that is subsequently deserialized by the affected component. This processing can enable attacker-controlled code execution and compromise the confidentiality, integrity, and availability of the host system. The issue affects NetWeaver instances with Visual Composer enabled that have not applied SAP Security Note 3604119.
