Vulnerability Title
Hardcoded session key in Zabbix 7.4
Source: CVE Program / CVE List V5
Vulnerability Description
In Zabbix 7.4 the cryptographic key used for signing Frontend sessions has been erroneously written to the database seed. Currently the only known exploitation scenario is for deployments that utilize both - SAML authentication and guest users. In such cases the key can be used to forge valid session cookies, potentially leading to unauthorized access. For other Zabbix deployments this does not have a known impact.
