CVE-2018-10925

postgresql: Missing authorization and memory disclosure in INSERT ... ON CONFLICT DO UPDATE statements

Published Aug 9, 2018 CVSS 3.1 · 8.1 High EPSS 2.2% KEV · Not listed
Description
It was discovered that PostgreSQL versions before 10.5, 9.6.10, 9.5.14, 9.4.19, and 9.3.24 failed to properly check authorization on certain statements involved with "INSERT ... ON CONFLICT DO UPDATE". An attacker with "CREATE TABLE" privileges could exploit this to read arbitrary bytes server memory. If the attacker also had certain "INSERT" and limited "UPDATE" privileges to a particular table, they could exploit this to update other columns in the same table.
