The vulnerability is caused by a misconfiguration in the application's authentication filters.\n\n\n\nConsequently, the server responds with a Set-Cookie header containing a valid JSESSIONID. This session cookie decodes to a JSON Web Token (JWT) granting maximum cluster administrative privileges. Successful exploitation allows the attacker to execute root-level commands on all Controller VMs (CVMs) in the cluster, leading to complete cluster destruction and unauthorized access to VM memory and virtual disks.","state":0,"publishedAt":"2026-10-15T17:10:29.432+00:00","modifiedAt":"2026-10-15T19:14:57.185+00:00","affected":[{"ecosystem":"Vendor product","name":"Acropolis Operating System (AOS)","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"Nutanix\",\n                    \"product\": \"Acropolis Operating System (AOS)\",\n                    \"modules\": [\n                        \"Prism Gateway\"\n                    ],\n                    \"versions\": [\n                        {\n                            \"status\": \"affected\",\n                            \"version\": \"0\",\n                            \"lessThan\": \"7.3.1.18\",\n                            \"changes\": [\n                                {\n                                    \"at\": \"7.3.1.18\",\n                                    \"status\": \"unaffected\"\n                                }\n                            ],\n                            \"versionType\": \"custom\"\n                        },\n                        {\n                            \"status\": \"affected\",\n                            \"version\": \"7.5\",\n                            \"lessThan\": \"7.5.2\",\n                            \"changes\": [\n                                {\n                                    \"at\": \"7.5.2\",\n                                    \"status\": \"unaffected\"\n                                }\n                            ],\n                            \"versionType\": \"custom\"\n                        },\n                        {\n                            \"status\": \"affected\",\n                            \"version\": \"7.6\",\n                            \"lessThan\": \"7.6.0.8\",\n                            \"changes\": [\n                                {\n                                    \"at\": \"7.6.0.8\",\n                                    \"status\": \"unaffected\"\n                                }\n                            ],\n                            \"versionType\": \"custom\"\n                        }\n                    ],\n                    \"defaultStatus\": \"unaffected\"\n                }"}],"metrics":[{"system":"CVSS 4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:H/SI:H/SA:H/E:P/S:N/AU:Y/R:U/V:C/RE:H/U:Red","score":9.3,"severity":"CRITICAL"},{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","score":9.8,"severity":"CRITICAL"},{"system":"CVSS 2.0","vector":"AV:N/AC:L/Au:N/C:C/I:C/A:C","score":10,"severity":null}],"references":["https://download.nutanix.com/alerts/Security_Advisory_0058.pdf","https://portal.nutanix.com/page/documents/list?type=software&filterKey=software&filterVal=AOS","https://www.nutanix.com/support"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-84731","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-84731","identifiers":["CVE-2026-84731"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
