CVE-2026-2003

Name of the Vulnerable Software and Affected Versions PostgreSQL versions prior to 18.2 PostgreSQL versions prior to 17.8 PostgreSQL versions prior to 16.12 PostgreSQL versions prior to 15.16 PostgreSQL versions prior to 14.21

Description A flaw exists in PostgreSQL due to improper validation of the 'oidvector' type. This can allow a database user to reveal a limited amount of server memory. While the possibility of exposing confidential information through this method seems unlikely, it has not been entirely dismissed.

Recommendations Update to PostgreSQL version 18.2 or later. Update to PostgreSQL version 17.8 or later. Update to PostgreSQL version 16.12 or later. Update to PostgreSQL version 15.16 or later. Update to PostgreSQL version 14.21 or later.
