How the CVE Works
CVE-2025-50066 exploits a flaw in Oracle Database’s Materialized View component, affecting versions 19.3-19.27, 21.3-21.18, and 23.4-23.8. An attacker with high privileges (Execute on DBMS_REDEFINITION) and network access via Oracle Net can manipulate Materialized View data. The vulnerability allows unauthorized INSERT, UPDATE, or DELETE operations on accessible data. Due to high privilege requirements, exploitation is limited, leading to a low CVSS score (2.7). The attack vector is network-based, requiring no user interaction, but impacts only data integrity, not confidentiality or availability.
