CVE-2026-6474 is a medium severity vulnerability in PostgreSQL affecting versions prior to 18.4, 17.10, 16.14, 15.18, and 14.23. It involves an externally-controlled format string in the timeofday() function that allows an attacker to retrieve portions of server memory by using crafted timezone zones. The vulnerability has a CVSS score of 4.3 and does not require user interaction but does require low privileges. No known exploits are reported in the wild.

Integer wraparound in multiple PostgreSQL server features allows an unprivileged database user to cause the server to undersize an allocation and write out-of-bounds. This may execute arbitrary code as the operating system user running the database. In applications that pass gigabyte-scale user inputs to the relevant database functions, the application input provider may achieve a segmentation fault. Versions before PostgreSQL 18.4, 17.10, 16.14, 15.18, and 14.23 are affected.

Missing authorization in PostgreSQL CREATE TYPE allows an object creator to hijack other queries that use search_path to find user-defined types, including extension-defined types. That is to say, the victim will execute arbitrary SQL functions of the attacker's choice. Versions before PostgreSQL 18.4, 17.10, 16.14, 15.18, and 14.23 are affected.
