CVE-2026-23919 (opens in a new tab)How to fix?
Upgrade Debian:unstable zabbix to version 1:7.0.22+dfsg-1 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream zabbix package and not the zabbix package as distributed by Debian.
See How to fix? for Debian:unstable relevant fixed versions and status.
For performance reasons Zabbix Server/Proxy reuses JavaScript (Duktape) contexts (used in script items, JavaScript reprocessing, Webhooks). This can lead to confidentiality loss where a regular (non-super) Zabbix administrator leaks data for hosts they do not have access to. A fix has been released that makes the built in Zabbix JavaScript objects read-only, but please be advised that usage of global JavaScript variables is not recommended because their content could be leaked.
