  "account": "Zabbix agent versions earlier than 7.0.24 and 7.4.8 have a vulnerability (CVE-2026-59781) that enables privilege escalation via DLL loading during installation. This flaw arises due to incorrect file access permissions, allowing a local low-privileged attacker to place a malicious DLL in a location searched by the installer. When an administrator runs the vulnerable installer, it loads the attacker's DLL, executing arbitrary code with administrator privileges. The attacker's goal is to exploit the vulnerable installer and gain administrator privileges. The success of this attack depends on the attacker's ability to write to the DLL search path and an administrator running the vulnerable installer, which would allow the malicious DLL to take precedence over legitimate libraries. Although the vulnerability has a moderate severity rating (CVSS v4.0: 5.4, CVSS v3.1: 6.7), it requires local low privileges and user interaction. The vendor recommends updating to Zabbix agent 7.0.24, 7.4.8, or later to mitigate the risk.",
