CVE-2026-23919
Description
A flaw was found in Zabbix Server and Proxy. This vulnerability arises from the system's reuse of JavaScript (Duktape) contexts, which are execution environments for JavaScript code. A regular Zabbix administrator, even without superuser privileges, can exploit this to access and leak sensitive data from hosts they are not authorized to manage. This leads to a confidentiality loss, as information intended to be restricted becomes accessible.
