ALPINE-CVE-2026-120153: SQL Injection

Published Nov 12, 2026
·
Updated

SQL injection in PostgreSQL extension-script substitutions allows an attacker with database-level CREATE privilege to execute arbitrary code as the bootstrap superuser, via a schema or owner name containing newlines or other special substrings. This is similar to CVE-2023-39417, but it requires a non-bundled extension with a vulnerable script pattern. 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 database-level CREATE privilege. Exploitation also depends on a non-bundled extension being installed or used with a vulnerable extension-script substitution pattern.

2

Are standard PostgreSQL extensions affected?

The issue requires a non-bundled extension with a vulnerable script pattern. The provided information does not identify any specific extension as vulnerable.

3

Which PostgreSQL releases contain the fix?

Fixed releases are PostgreSQL 18.7, 17.12, 16.16, 15.20, and 14.25. Earlier releases in those version lines are affected.

4

What is the impact if exploitation succeeds?

Successful exploitation can allow arbitrary code execution as the bootstrap superuser. This can compromise confidentiality, integrity, and availability of the database environment.
