High severity, CVSS 8.5. EPSS: 0.5% chance of exploitation in the next 30 days.

A flaw was found in the `search-v2-operator` component.

This manipulation can override critical settings, leading to the replacement of container images. This ultimately results in container image injection on the managed cluster, potentially compromising its integrity.
