MEDIUM 5.4EPSS 0.30%

Does this matter?

Lower severity and a low EPSS score (0.30%). Track it; it rarely justifies an emergency change on its own.

Description

An attacker can include malicious PHP code in a module's `install()` method which will then be executed upon installation, enabling remote code execution with the privileges of the web server.
