- Exploitation
- CISA lists CVE-2026-25089 as exploited in the wild.
France's CERT has issued an advisory regarding multiple security vulnerabilities affecting a wide range of Fortinet products. The flaws impact FortiOS versions 7.2.x through 7.6.x, FortiProxy versions 7.2.x through 7.6.x, FortiPortal versions up to 7.4.x, and various FortiSandbox deployments including Cloud and PaaS editions. The vulnerabilities enable remote attackers to execute arbitrary code and compromise data confidentiality.
Fortinet has released patches addressing three distinct CVEs: CVE-2025-67862, CVE-2026-25089, and CVE-2026-49938. The advisory references three separate Fortinet security bulletins (FG-IR-26-140, FG-IR-26-141, and FG-IR-26-143) published on June 9, 2026. Organizations running affected versions should prioritize patching to FortiOS 7.2.11+, 7.4.8+, or 7.6.3+; FortiProxy 7.2.15+, 7.4.11+, or 7.6.4+; FortiPortal 7.2.9+ or 7.4.8+; and FortiSandbox 4.4.9+ or 5.0.6+ depending on their deployment.
The affected products are widely deployed in enterprise network security architectures, making these vulnerabilities particularly significant for organizations relying on Fortinet infrastructure for perimeter defense, SSL inspection, and threat analysis. Given the remote code execution capability, these flaws represent a critical attack surface that threat actors may seek to exploit.

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 16,445 reports from 149 sources, 666 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.
