- Exploitation
- No exploitation in the wild and no public exploit is recorded for the CVEs named.
CERT-FR published an advisory summarizing multiple vulnerabilities affecting a broad range of Fortinet products, including FortiOS, FortiAnalyzer, FortiManager, FortiClient, FortiPAM, FortiSandbox, FortiSIEM, and FortiSOAR. The flaws collectively allow attackers to achieve remote code execution, privilege escalation, remote denial of service, data integrity and confidentiality breaches, and security policy bypass, depending on the specific product and CVE. No indication of active exploitation in the wild is mentioned in this advisory.
The affected versions span numerous Fortinet product lines and their respective cloud/PaaS variants, indicating a coordinated patch cycle covering 11 separate Fortinet PSIRT bulletins (FG-IR-26-164 through FG-IR-26-174) released on 8 September 2026. Eleven CVEs were referenced (CVE-2026-22575, CVE-2026-26084, and CVE-2026-84385 through CVE-2026-84393), though the advisory does not break down which CVE maps to which specific product or vulnerability type.
Defenders operating any of the listed Fortinet products should prioritize patching to the fixed versions identified (e.g., FortiOS 7.6.7, FortiManager 7.6.5/7.4.11, FortiSIEM 7.5.2, FortiPAM 1.9.1, FortiSandbox 5.2.1/5.0.7/4.4.10, FortiSOAR 7.6.7/7.5.4, FortiClient Windows 7.4.7, FortiPAM Chrome Extension 8.0.1.123, FortiMonitorOnSight 7.2.8). Given the breadth of affected products—including management, security orchestration, and endpoint platforms—organizations should treat this as a priority patch cycle even absent confirmed in-the-wild exploitation, given Fortinet products' history of being targeted post-disclosure.

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.
