CVE-2025-42928Network attack vector

Privileged remote code execution

Published Dec 9, 2025 · Updated Feb 26, 2026

Insecure deserialization in SAP jConnect for JDBC 16.0.4 and 16.1 allows remote authenticated users with high privileges to execute code. SAP's public bulletin does not identify the affected connection property, deserialization call, or object type that processes the crafted input. Reachability requires high privileges and specific undisclosed conditions; successful exploitation runs code with the host application's access.
