An attacker could exploit this vulnerability by connecting to the Snort 3 control channel socket as a local user. A successful exploit could allow the attacker to execute arbitrary commands as well as read and write Snort 3 process memory.","published":"2026-10-21T17:19:10.000Z","lastModified":"2026-10-22T14:17:50.000Z","status":"Awaiting Analysis","sourceIdentifier":"psirt@cisco.com","cvss":{"version":"3.1","score":7.8,"severity":"HIGH","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"},"cwe":["CWE-306"],"affected":[],"epss":{"score":0.00177,"percentile":0.07217,"date":"2026-10-26","history":[{"date":"2026-10-22","score":0.00136,"percentile":0.02754}]},"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 (0.18%).
