What is CVE-2020-10733?

The PostgreSQL installer for versions 9.5 through 12 has a vulnerability that allows an attacker, with proper permissions, to place malicious executables in directories searched by the installer. Due to the lack of fully-qualified paths when invoking system-provided executables, this allows those malicious executables to take precedence, potentially leading to execution of arbitrary code with administrative privileges during the installation process.

Affected Version(s)

PostgreSQL 9.5, 9.6, 10, 11, 12
