Impact

Improper authorization in Azure Red Hat OpenShift (ARO) allows an authenticated attacker to elevate privileges over a network. This privilege escalation enables the attacker to act beyond the intended scope of their account.

Affected Systems

Microsoft Azure Red Hat OpenShift. No specific version information is available.

Risk and Exploitability

The CVSS score of 9.1 indicates high severity. The EPSS score of less than 1% suggests that exploitation is unlikely to be widespread, and the vulnerability is not listed in the CISA KEV catalog. The likely attack vector is over the network after the attacker has authenticated, enabling bypass of authorization controls and privilege escalation.
