{"id":"UBUNTU-CVE-2026-84989","details":"ntopng is a web-based network traffic monitoring application. In versions 6.7.0 through 6.7.260717, two REST v2 endpoints that manage ntopng's tag/badge feature — `POST /lua/rest/v2/delete/tag/tag.lua` and `POST /lua/rest/v2/edit/tag/tag.lua` — perform no authorization check at all. Any authenticated user, including a non-administrator (\"unprivileged\") account, can delete or rename any tag in the system, including tags created by an administrator. Version 6.7.260718 contains a fix.","modified":"2026-09-16T11:43:10Z","published":"2026-09-03T15:17:00Z","upstream":["CVE-2026-84989"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2026-84989"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2026-84989"},{"type":"REPORT","url":"https://github.com/ntop/ntopng/commit/0e41f24b367fb9caf750459da67827326e3289e8"},{"type":"REPORT","url":"https://github.com/ntop/ntopng/security/advisories/GHSA-43p9-5758-wwq8"}],"affected":[{"package":{"name":"ntopng","ecosystem":"Ubuntu:Pro:16.04:LTS","purl":"pkg:deb/ubuntu/ntopng?arch=source&distro=esm-apps%2Fxenial"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.2.1+dfsg1-2ubuntu1","2.0+dfsg1-1","2.2+dfsg1-1","2.2+dfsg1-1build1","2.2+dfsg1-1ubuntu0.1~esm2"],"ecosystem_specific":{"binaries":[{"binary_version":"2.2+dfsg1-1ubuntu0.1~esm2","binary_name":"ntopng"},{"binary_name":"ntopng-data","binary_version":"2.2+dfsg1-1ubuntu0.1~esm2"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-84989.json"}},{"package":{"name":"ntopng","ecosystem":"Ubuntu:Pro:18.04:LTS","purl":"pkg:deb/ubuntu/ntopng?arch=source&distro=esm-apps%2Fbionic"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.4+dfsg1-3","2.4+dfsg1-4","3.2+dfsg1-1","3.2+dfsg1-1ubuntu0.1~esm2"],"ecosystem_specific":{"binaries":[{"binary_version":"3.2+dfsg1-1ubuntu0.1~esm2","binary_name":"ntopng"},{"binary_name":"ntopng-data","binary_version":"3.2+dfsg1-1ubuntu0.1~esm2"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-84989.json"}},{"package":{"name":"ntopng","ecosystem":"Ubuntu:20.04:LTS","purl":"pkg:deb/ubuntu/ntopng?arch=source&distro=focal"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["3.8+dfsg1-2.1build3"],"ecosystem_specific":{"binaries":[{"binary_name":"ntopng","binary_version":"3.8+dfsg1-2.1build3"},{"binary_version":"3.8+dfsg1-2.1build3","binary_name":"ntopng-data"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-84989.json"}},{"package":{"name":"ntopng","ecosystem":"Ubuntu:22.04:LTS","purl":"pkg:deb/ubuntu/ntopng?arch=source&distro=jammy"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["5.2.1+dfsg1-1"],"ecosystem_specific":{"binaries":[{"binary_version":"5.2.1+dfsg1-1","binary_name":"ntopng"},{"binary_version":"5.2.1+dfsg1-1","binary_name":"ntopng-data"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-84989.json"}},{"package":{"name":"ntopng","ecosystem":"Ubuntu:24.04:LTS","purl":"pkg:deb/ubuntu/ntopng?arch=source&distro=noble"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["5.2.1+dfsg1-1","5.2.1+dfsg1-1ubuntu1","5.2.1+dfsg1-1ubuntu3","5.2.1+dfsg1-1ubuntu4"],"ecosystem_specific":{"binaries":[{"binary_name":"ntopng","binary_version":"5.2.1+dfsg1-1ubuntu4"},{"binary_name":"ntopng-data","binary_version":"5.2.1+dfsg1-1ubuntu4"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-84989.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:L"},{"type":"Ubuntu","score":"medium"}]}
