# CVE-2025-58034: Fortinet FortiWeb OS Command Injection Vulnerability

**Signal:** Exploited: patch now if you run it. CISA has confirmed exploitation in the wild. (Computed from CISA KEV, EPSS and CVSS; not an editorial verdict.)

## Should you act?

- Yes, if you run Fortinet FortiWeb. CISA added this CVE to its Known Exploited Vulnerabilities catalog on 2025-11-18, which means there is reliable evidence of exploitation in the wild. US federal agencies must remediate by 2025-11-25 ; treat that as the outer limit, not the target.
- EPSS 54.7% , percentile 99: FIRST’s model estimates a 54.7% chance of exploitation activity in the next 30 days, higher than 99% of all scored CVEs (very high). EPSS is a probability, not a verdict.
- Needs an account (high (admin)). Exposure depends on who can log in.
- Editorial verdict: Act now. FortiWeb CVE-2025-64446: Exploited Unauthenticated Takeover — Any FortiWeb still below the fixed builds with its web GUI reachable from the internet should be presumed compromised and rebuilt, not just patched.
