Zabbix Zabbix
CVE-2026-23924
Zabbix Agent 2 Docker plugin does not properly sanitize the 'docker.container_info' parameters when forwarding them to the Docker daemon. An attacker capable of invoking Agent 2 can read arbitrary files from running Docker containers by injecting them via the Docker archive API.
What this means for your business
- It affects Zabbix. It matters if your company, or a supplier that handles your data, runs it.
- An attacker can use it remotely, over a network, with an administrator login, and without anyone at your company clicking anything.
What to do
- 1Check whether your company or your suppliers run Zabbix, and which version. The affected versions are listed further down this page.
- 2If you do, apply the vendor's fix. A patch or vendor advisory has been published.
