CVE-2026-56160
This vulnerability allows an attacker who already has some level of access to Azure Red Hat OpenShift to gain higher privileges over the network. It can lead to full control of the cluster. The flaw is due to improper authorization checks.
No official fix yet. If none appears within 45 days of first tracking, this entry is removed automatically.
Who is affected
Azure Red Hat OpenShift (ARO) users, especially those with network access to the cluster such as cloud administrators and developers.
Real-world impact
An attacker could take over the cluster, modify or delete resources, and potentially access sensitive data.
Why this severity
The CVSS score of 9.1 reflects a critical vulnerability: the attack can be performed over the network with low complexity, requires high privileges, no user interaction, and results in complete compromise of confidentiality, integrity, and availability.
What to do about it
- ›Restrict network access to the ARO cluster to trusted IP ranges.
- ›Enforce least privilege for all users and services interacting with the cluster.
- ›Monitor for unauthorized privilege escalation or configuration changes.
