An authenticated user with limited privileges can remotely bypass the intended access control of the web management interface and modify the Smart Polling discovery configuration. This allows the attacker to disrupt the visibility of assets in the monitored network.","state":0,"publishedAt":"2026-09-08T13:56:38.077+00:00","modifiedAt":"2026-10-15T01:18:23.954+00:00","affected":[{"ecosystem":"Vendor product","name":"Guardian","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"Nozomi Networks\",\n                    \"product\": \"Guardian\",\n                    \"versions\": [\n                        {\n                            \"status\": \"affected\",\n                            \"version\": \"0\",\n                            \"lessThan\": \"26.3.0\",\n                            \"versionType\": \"semver\"\n                        }\n                    ],\n                    \"defaultStatus\": \"unaffected\"\n                }"},{"ecosystem":"Vendor product","name":"CMC","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"Nozomi Networks\",\n                    \"product\": \"CMC\",\n                    \"versions\": [\n                        {\n                            \"status\": \"affected\",\n                            \"version\": \"0\",\n                            \"lessThan\": \"26.3.0\",\n                            \"versionType\": \"semver\"\n                        }\n                    ],\n                    \"defaultStatus\": \"unaffected\"\n                }"}],"metrics":[{"system":"CVSS 4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:L/VA:L/SC:N/SI:N/SA:N","score":5.3,"severity":"MEDIUM"},{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:L","score":5.4,"severity":"MEDIUM"}],"references":["https://security.nozominetworks.com/NN-2026:17-01"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-33391","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-33391","identifiers":["CVE-2026-33391"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
