An object-relational database management system (ORDBMS) combines classic relational tables and SQL with object-style features such as custom data types, inheritance, and stored procedures. PostgreSQL is a well-known example. The goal is to keep the structured querying of a relational database while supporting richer application data models.
In cyber security, ORDBMS platforms matter because they often sit close to sensitive business logic and critical data. Their object-style extensions can expand the attack surface through custom functions, plugins, formatting logic, or application-specific code paths. Attackers may target these features to trigger crashes, bypass controls, or reach privileged operations. Defenders should inventory versions, review exposed database services, and test whether risky code paths are reachable in their configuration. In practice, secure ORDBMS use means patching quickly, limiting access, and monitoring unusual database errors or behavior.
