Bottom Line: Red Hat Satellite contains multiple vulnerabilities that allow attackers to gain administrator privileges, bypass authentication, and cause data loss.
Red Hat Satellite contains several security flaws in the components Foreman, python-pillow, and Go dependencies. An attacker can exploit these to gain administrator rights, bypass authentication, or trigger denial-of-service conditions.
Red Hat Satellite is widely deployed in infrastructure environments for managing Red Hat systems. The current advisory addresses multiple vulnerabilities in critical components: The management module Foreman, the Python image library pillow, and Go-based dependencies contain security flaws that collectively represent a significant risk.
The identified vulnerabilities enable an attacker to obtain unauthorized administrator privileges, circumvent existing authentication mechanisms, manipulate data, or exfiltrate confidential information. Furthermore, denial-of-service scenarios can be triggered that jeopardize the operation of the satellite instance.
As a CISO, this requires a timely inventory of all Red Hat Satellite installations in your own infrastructure and prioritized patch planning. The range of attack vectors – from privilege escalation to availability disruption – makes swift remediation necessary. The German Federal Office for Information Security (BSI) has included the advisory under WID-SEC-2026-2166.
