CVSS 9.8 EPSS 92% 2 public exploits Fix deadline passed 21 November 2025

What it is

Fortinet FortiWeb contains a relative path traversal vulnerability that may allow an unauthenticated attacker to execute administrative commands on the system via crafted HTTP or HTTPS requests.

Why we say that

  • EPSS puts exploitation in the next 30 days at 92%
  • 2 public exploits published
  • CISA's federal remediation deadline (2025-11-21) has passed
  • CVSS 9.8 critical
  • Listed in the CISA Known Exploited Vulnerabilities catalogue

Every line above comes from a named public source. Where the evidence is thin, we say so rather than inventing confidence — see methodology.

What to do

Apply mitigations per vendor instructions, follow applicable BOD 22-01 guidance for cloud services, or discontinue use of the product if mitigations are unavailable.

Public exploit code

Indexed from Exploit-DB. Presence of code raises urgency; absence does not mean safety.

What it costs when this goes wrong
