EchelonGraph scoreMEDIUM confidence

This high-severity CVE scores 7.7 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit probability: 0.2%, top 89% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

A privilege-escalation issue in the Portworx Operator when deployed on Red Hat OpenShift (OCP). Only under specific conditions during the initial provisioning of a Portworx storage cluster, a user holding only limited, namespace-scoped permissions could cause the operator to grant broader access than intended, potentially resulting in elevated privileges within the Kubernetes cluster.
