What is CVE-2026-59785?

An access control vulnerability in Zabbix's frontend allows users with read permissions to filter search results by sensitive fields not displayed to them. This flaw potentially exposes stored IPMI and PSK credentials, as a user can guess these values and ascertain their validity based on the search results. Consequently, unauthorized users could exploit this flaw to gain access to sensitive information.
