{"schemaVersion":3,"id":"CVE-2026-82369","aliases":[],"status":"published","duplicateOf":null,"title":null,"description":"Insufficient input sanitization of shell metacharacters in the Brocade SANnav CLI scripting component permits authenticated users to break out of restricted execution contexts on managed switches. An attacker with command execution permissions can leverage this flaw to run unauthorized shell commands across target fabric switches, bypassing command allow-lists and obtaining full administrative switch access. This vulnerability affects all Brocade SANnav versions before 3.0.1a.","dates":{"published":"2026-09-23T20:45:24.825Z","modified":"2026-10-01T20:15:25.814Z","reserved":null,"kevAdded":[],"kevDue":[]},"cvss":{"headline":{"score":8.6,"severity":"high","version":"4.0","versionLabel":"v4.0","source":"CVE.org","vector":"CVSS:4.0/AV:A/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","computed":false,"selection":"backend-summary"},"metrics":[{"version":"4.0","versionLabel":"v4.0","source":"CVE.org","score":8.6,"severity":"high","vector":"CVSS:4.0/AV:A/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","exploitability":null,"impact":null,"computed":false},{"version":"4.0","versionLabel":"v4.0","source":"NVD","score":8.6,"severity":"high","vector":"CVSS:4.0/AV:A/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X","exploitability":null,"impact":null,"computed":false}]},"epss":{"probability":0.00512,"percentile":0.42506,"severity":"low","asOf":"2026-10-20T00:00:00.000Z","change":{"pp":null,"baselineDate":null,"baselineScore":null},"history":[{"date":"2026-09-24T00:00:00.000Z","score":0.00512,"percentile":null},{"date":"2026-09-25T00:00:00.000Z","score":0.00512,"percentile":null},{"date":"2026-09-26T00:00:00.000Z","score":0.00512,"percentile":null},{"date":"2026-09-27T00:00:00.000Z","score":0.00512,"percentile":null},{"date":"2026-09-28T00:00:00.000Z","score":0.00512,"percentile":null},{"date":"2026-09-29T00:00:00.000Z","score":0.00512,"percentile":null},{"date":"2026-09-30T00:00:00.000Z","score":0.00512,"percentile":null},{"date":"2026-10-01T00:00:00.000Z","score":0.00512,"percentile":null},{"date":"2026-10-02T00:00:00.000Z","score":0.00512,"percentile":null},{"date":"2026-10-03T00:00:00.000Z","score":0.00512,"percentile":null},{"date":"2026-10-04T00:00:00.000Z","score":0.00512,"percentile":null},{"date":"2026-10-05T00:00:00.000Z","score":0.00512,"percentile":null},{"date":"2026-10-06T00:00:00.000Z","score":0.00512,"percentile":null},{"date":"2026-10-07T00:00:00.000Z","score":0.00512,"percentile":null},{"date":"2026-10-08T00:00:00.000Z","score":0.00512,"percentile":null},{"date":"2026-10-09T00:00:00.000Z","score":0.00512,"percentile":null},{"date":"2026-10-10T00:00:00.000Z","score":0.00512,"percentile":null},{"date":"2026-10-11T00:00:00.000Z","score":0.00512,"percentile":null},{"date":"2026-10-12T00:00:00.000Z","score":0.00512,"percentile":null},{"date":"2026-10-13T00:00:00.000Z","score":0.00512,"percentile":null},{"date":"2026-10-14T00:00:00.000Z","score":0.00512,"percentile":null},{"date":"2026-10-15T00:00:00.000Z","score":0.00512,"percentile":null},{"date":"2026-10-16T00:00:00.000Z","score":0.00512,"percentile":null},{"date":"2026-10-17T00:00:00.000Z","score":0.00512,"percentile":null},{"date":"2026-10-18T00:00:00.000Z","score":0.00512,"percentile":null},{"date":"2026-10-19T00:00:00.000Z","score":0.00512,"percentile":null},{"date":"2026-10-20T00:00:00.000Z","score":0.00512,"percentile":0.42506}],"last30":[{"date":"2026-09-24T00:00:00.000Z","score":0.00512,"percentile":null},{"date":"2026-09-25T00:00:00.000Z","score":0.00512,"percentile":null},{"date":"2026-09-26T00:00:00.000Z","score":0.00512,"percentile":null},{"date":"2026-09-27T00:00:00.000Z","score":0.00512,"percentile":null},{"date":"2026-09-28T00:00:00.000Z","score":0.00512,"percentile":null},{"date":"2026-09-29T00:00:00.000Z","score":0.00512,"percentile":null},{"date":"2026-09-30T00:00:00.000Z","score":0.00512,"percentile":null},{"date":"2026-10-01T00:00:00.000Z","score":0.00512,"percentile":null},{"date":"2026-10-02T00:00:00.000Z","score":0.00512,"percentile":null},{"date":"2026-10-03T00:00:00.000Z","score":0.00512,"percentile":null},{"date":"2026-10-04T00:00:00.000Z","score":0.00512,"percentile":null},{"date":"2026-10-05T00:00:00.000Z","score":0.00512,"percentile":null},{"date":"2026-10-06T00:00:00.000Z","score":0.00512,"percentile":null},{"date":"2026-10-07T00:00:00.000Z","score":0.00512,"percentile":null},{"date":"2026-10-08T00:00:00.000Z","score":0.00512,"percentile":null},{"date":"2026-10-09T00:00:00.000Z","score":0.00512,"percentile":null},{"date":"2026-10-10T00:00:00.000Z","score":0.00512,"percentile":null},{"date":"2026-10-11T00:00:00.000Z","score":0.00512,"percentile":null},{"date":"2026-10-12T00:00:00.000Z","score":0.00512,"percentile":null},{"date":"2026-10-13T00:00:00.000Z","score":0.00512,"percentile":null},{"date":"2026-10-14T00:00:00.000Z","score":0.00512,"percentile":null},{"date":"2026-10-15T00:00:00.000Z","score":0.00512,"percentile":null},{"date":"2026-10-16T00:00:00.000Z","score":0.00512,"percentile":null},{"date":"2026-10-17T00:00:00.000Z","score":0.00512,"percentile":null},{"date":"2026-10-18T00:00:00.000Z","score":0.00512,"percentile":null},{"date":"2026-10-19T00:00:00.000Z","score":0.00512,"percentile":null},{"date":"2026-10-20T00:00:00.000Z","score":0.00512,"percentile":0.42506}]},"kev":{"state":"not-listed","entries":[],"listedCount":0,"totalCatalogs":3,"catalogs":[{"source":"cisa",
