# CVE-2022-23133: Stored XSS in host groups configuration window in Zabbix Frontend

- Severity: CVSS 6.3 (Medium), CNA
- Vector: CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:L
- Known exploited (CISA KEV): no
- Published: 2022-01-13 · Updated: 2025-11-03

## Affected

- Zabbix Frontend: 5.0.0 – 5.0.18, 5.4.0 – 5.4.8

## Description

An authenticated user can create a hosts group from the configuration with XSS payload, which will be available for other users. When XSS is stored by an authenticated malicious actor and other users try to search for groups during new host creation, the XSS payload will fire and the actor can steal session cookies and perform session hijacking to impersonate users or take over their accounts.
