What is CVE-2019-10127?

A security vulnerability in the Windows installer for PostgreSQL affects versions 11.x prior to 11.3, where the Access Control List (ACL) for both the binary installation and data directory remains open to inherited permissions. Consequently, an attacker with an unprivileged Windows or PostgreSQL account can exploit this flaw to execute arbitrary code or gain unauthorized access to sensitive data, bypassing the read access limitations enforced by the database. The vulnerability underscores the necessity for stricter ACL configurations to prevent potential data breaches and protect system integrity.
