Because that state is trusted rather than re-validated, operations may be carried out beyond the user's authorized scope, including changes to cluster-wide security configuration. Successful triggering this issue requires an authenticated session directly against a cluster member and can result in unauthorized access to and modification of data across the cluster.","cvssScore":7.2,"cvssSeverity":"HIGH","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H","cwes":["CWE-250"],"vendors":[],"products":[],"references":[{"url":"https://jira.mongodb.org/browse/SERVER-133600","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":null}
