An attacker could exploit this vulnerability by sending API requests to a specific endpoint. A successful exploit could allow the attacker to gain administrator-level control over edge nodes that are managed by Cisco Meeting Management.","published":"2025-01-22T17:15:13.000Z","lastModified":"2026-06-17T08:40:49.000Z","status":"Analyzed","sourceIdentifier":"psirt@cisco.com","cvss":{"version":"3.1","score":9.9,"severity":"CRITICAL","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H"},"cwe":["CWE-274"],"affected":["cisco/meeting management"],"epss":{"score":0.01193,"percentile":0.67796,"date":"2026-10-26","history":[]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"high","text":"High impact if exploited, but EPSS currently rates exploitation as unlikely (1.19%).
