The Operator creates a ServiceAccount with *ClusterRole* upon deployment of the *Namespace-Scoped* Custom Resource MonitorStack. This issue allows an adversarial Kubernetes Account with only namespaced-level roles, for example, a tenant controlling a namespace, to create a MonitorStack in the authorized namespace and then elevate permission to the cluster level by impersonating the ServiceAccount created by the Operator, resulting in privilege escalation and other issues."},{"lang":"es","value":"Se encontró una vulnerabilidad en el Operador de Observabilidad. El Operador crea una ServiceAccount con ClusterRole al desplegar el Recurso Personalizado MonitorStack de ámbito de espacio de nombres (Namespace-Scoped). Este problema permite que una Cuenta de Kubernetes adversaria con solo roles a nivel de espacio de nombres, por ejemplo, un inquilino que controla un espacio de nombres, cree un MonitorStack en el espacio de nombres autorizado y luego eleve los permisos al nivel de clúster al suplantar la identidad de la ServiceAccount creada por el Operador, lo que resulta en escalada de privilegios y otros problemas."}],"affected":[{"source":"secalert@redhat.com","affectedData":[{"vendor":"rhobs","product":"observability-operator","defaultStatus":"unaffected","collectionURL":"https://github.com/rhobs/observability-operator","packageName":"observability-operator","versions":[{"version":"0","lessThan":"1.3.0","versionType":"semver","status":"affected"}]},{"vendor":"Red Hat","product":"Cluster Observability Operator 1.3.1","defaultStatus":"affected","collectionURL":"https://catalog.redhat.com/software/containers/","packageName":"cluster-observability-operator/cluster-observability-rhel9-operator","cpes":["cpe:/a:redhat:cluster_observability_operator:1.3::el9"],"versions":[{"version":"1.3.0-1762825457","lessThan":"*","versionType":"rpm","status":"unaffected"}]}]}],"metrics":{"cvssMetricV31":[{"source":"secalert@redhat.com","type":"Secondary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","baseScore":8.8,"baseSeverity":"HIGH","attackVector":"NETWORK","attackComplexity":"LOW","privilegesRequired":"LOW","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"HIGH","integrityImpact":"HIGH","availabilityImpact":"HIGH"},"exploitabilityScore":2.8,"impactScore":5.9}],"ssvcV203":[{"source":"134c704f-9b21-4f2e-91b3-4a467353bcc0","ssvcData":{"timestamp":"2025-11-12T20:47:54.311119Z","id":"CVE-2025-2843","options":[{"exploitation":"none"},{"automatable":"no"},{"technicalImpact":"total"}],"role":"CISA Coordinator","version":"2.0.3"}}]},"weaknesses":[{"source":"secalert@redhat.com","type":"Secondary","description":[{"lang":"en","value":"CWE-266"}]}],"references":[{"url":"https://access.redhat.com/errata/RHSA-2025:21146","source":"secalert@redhat.com"},{"url":"https://access.redhat.com/security/cve/CVE-2025-2843","source":"secalert@redhat.com"},{"url":"https://bugzilla.redhat.com/show_bug.cgi?id=2355222","source":"secalert@redhat.com"}]}
