Does this matter?

Lower severity and a low EPSS score (0.67%). Track it; it rarely justifies an emergency change on its own.

Description

Improper input validation allows authenticated attackers with actioner privilege to run elevated arbitrary commands on connected hosts via malicious commands injected into the instruction’s input field. Users of 1E Client version 24.5 or higher are not affected.
