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.","published":"2025-11-12T16:36:04.735Z","modified":"2026-09-22T03:30:41.831585360Z","cvss":{"score":8.8,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Go","name":"github.com/rhobs/observability-operator","fixedVersion":"1.3.0"}],"fix":null,"references":[{"type":"WEB","url":"https://catalog.redhat.com/software/containers/"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2025:21146"},{"type":"ADVISORY","url":"https://access.redhat.com/security/cve/CVE-2025-2843"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/2xxx/CVE-2025-2843.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-2843"},{"type":"REPORT","url":"https://bugzilla.redhat.com/show_bug.cgi?id=2355222"},{"type":"PACKAGE","url":"https://github.com/rhobs/observability-operator"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-09-22T03:30:41.831585360Z"}}
