What to check
- Applies to
- The 11 CVEs named below. Whether you run an affected version is not assessed: check the versions the source lists.
- Exploitation
- No exploitation in the wild and no public exploit is recorded for the CVEs named.
CERT-FR has published an advisory covering multiple vulnerabilities discovered in Zabbix, an open-source monitoring solution widely used for IT infrastructure oversight. The flaws affect Zabbix versions 6.x prior to 6.0.48, 7.4.x prior to 7.4.13, and 7.x prior to 7.0.29. Impacts include remote denial of service, breaches of data confidentiality and integrity, security policy bypass, and indirect remote code injection via cross-site scripting (XSS).
Eleven CVEs are referenced in this advisory, corresponding to eleven separate Zabbix security bulletins (ZBX-28067 through ZBX-28077) published by the vendor on 18 August 2026. No indication of active exploitation is provided in the advisory; it is a standard vendor-patch notification. Organizations running affected Zabbix versions should apply the vendor-supplied patches referenced in the official Zabbix security bulletins as soon as practicable, particularly given Zabbix's common deployment in monitoring critical infrastructure and enterprise networks.

What this brief leaves out
This page is the free tier: the write-up, the severity, the names. In the app the same report carries live profiles of the CVEs it names. The paid plans add the security research and news reporting the free tier leaves out.
It sits in a corpus of 16,433 reports from 149 sources, 661 of them written in the last seven days, and it grows through the day.
A new account starts with three days of all of it, no card, then keeps the government and CERT reporting free. Slack alerts are a paid-plan feature: name the vendors you run and Slack hears about the reports that touch them, not the rest of the week's. Nothing is charged unless you subscribe.
