CVE-2026-23933 (opens in a new tab)How to fix?
Upgrade zabbix/zabbix to version 7.4.11 or higher.
Overview
Affected versions of this package are vulnerable to Use of Hard-coded Password in the settings.session_key process. An attacker can gain unauthorized access by forging valid session cookies. This is only exploitable if both SAML authentication and guest users are enabled.
Workaround
This vulnerability can be mitigated by manually clearing the pre-seeded session key from the database by setting the value of 'settings.session_key' to an empty string, allowing the frontend to generate a new random key.
