ALPINE-CVE-2026-116331: High severity alpine/postgresql15 vulnerability

Published Nov 12, 2026
·
Updated

Type confusion in PostgreSQL min/max aggregate optimization allows an object creator to execute arbitrary code as the operating system user running the database, via a user-defined aggregate whose SORTOP option causes the planner to treat the aggregate's input and result as the same type when they differ. Versions before PostgreSQL 18.7, 17.12, 16.16, 15.20, and 14.25 are affected.

Frequently Asked Questions

1

Who can exploit this issue?

An attacker needs privileges to create a user-defined aggregate. The vulnerable aggregate must use the SORTOP option and have different input and result types.

2

What level of access could successful exploitation provide?

Successful exploitation can execute arbitrary code as the operating system user running the PostgreSQL database. This can affect the confidentiality, integrity, and availability of the database host.

3

Which PostgreSQL releases contain fixes?

The issue is fixed in PostgreSQL 18.7, 17.12, 16.16, 15.20, and 14.25. Earlier versions in those release lines are affected.
