{"id":"DEBIAN-CVE-2026-23928","details":"The Item history widget (in Zabbix 7.0+) or the Plain text widget (in Zabbix 6.0) can execute injected JavaScript when HTML display is enabled. This can allow an attacker to perform unauthorized actions depending on which user opens a dashboard containing these widgets. The malicious JavaScript would have to come from a monitored host controlled by the attacker. Note: the Item history widget is a replacement for the Plain text widget since Zabbix 7.0.","modified":"2026-09-19T23:00:08.493682079Z","published":"2026-05-06T08:16:03.100Z","upstream":["CVE-2026-23928"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-23928"}],"affected":[{"package":{"name":"zabbix","ecosystem":"Debian:12","purl":"pkg:deb/debian/zabbix?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1:6.0.14+dfsg-1","1:6.0.23+dfsg-1","1:6.0.23+dfsg-1~bpo12+1","1:6.0.24+dfsg-1","1:6.0.25+dfsg-1","1:6.0.29+dfsg-1","1:7.0.0+dfsg-1","1:7.0.0+dfsg-2","1:7.0.0+dfsg-2~bpo12+1","1:7.0.1+dfsg-1","1:7.0.1+dfsg-1~bpo12+1","1:7.0.10+dfsg-1","1:7.0.10+dfsg-2","1:7.0.2+dfsg-1","1:7.0.2+dfsg-1~bpo12+1","1:7.0.22+dfsg-1","1:7.0.22+dfsg-1.1","1:7.0.22+dfsg-1~bpo13+1","1:7.0.22+dfsg-1~deb13u1","1:7.0.27+dfsg-1","1:7.0.29+dfsg-1","1:7.0.29+dfsg-2","1:7.0.3+dfsg-1","1:7.0.5+dfsg-1","1:7.0.5+dfsg-1~bpo12+1","1:7.0.6+dfsg-1","1:7.0.9+dfsg-1","1:7.0.9+dfsg-1~bpo12+1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-23928.json"}},{"package":{"name":"zabbix","ecosystem":"Debian:13","purl":"pkg:deb/debian/zabbix?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1:7.0.10+dfsg-2","1:7.0.22+dfsg-1","1:7.0.22+dfsg-1.1","1:7.0.22+dfsg-1~bpo13+1","1:7.0.22+dfsg-1~deb13u1","1:7.0.27+dfsg-1","1:7.0.29+dfsg-1","1:7.0.29+dfsg-2"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-23928.json"}},{"package":{"name":"zabbix","ecosystem":"Debian:14","purl":"pkg:deb/debian/zabbix?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1:7.0.27+dfsg-1"}]}],"versions":["1:7.0.10+dfsg-2","1:7.0.22+dfsg-1","1:7.0.22+dfsg-1.1","1:7.0.22+dfsg-1~bpo13+1","1:7.0.22+dfsg-1~deb13u1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-23928.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:H/UI:R/S:U/C:H/I:H/A:H"}]}
