Description

A flaw was found in the search-v2-operator. This vulnerability allows a privileged user, specifically a Custom Resource (CR) editor, to manipulate Search CR fields such as imageOverride, arguments, and environment variables without proper validation. By exploiting this, an attacker can mount arbitrary secrets into a search container's environment or replace the container image with an attacker-controlled one. This leads to privilege escalation and can result in a full cluster compromise due to the ServiceAccount's extensive impersonation permissions.
