Zabbix

Stored cross-site scripting (XSS) in Zabbix 6.0-7.4 allows authenticated attackers with high privileges to inject malicious JavaScript via monitored host data that executes when other users view dashboards containing Item history widgets (7.0+) or Plain text widgets (6.0). The attack requires the attacker to control a monitored host and the victim to open a dashboard with HTML display enabled in the affected widget. CVSS 7.3 reflects high impact but requires specific preconditions: high-privilege access (PR:H), user interaction (UI:P), and precise attack timing (AT:P). No CISA KEV listing or public exploit identified at time of analysis, with low immediate exploitation risk given the privilege requirements.
