CVE-2026-70467Network attack vector

Authenticated appliance request proxying via crafted GUI input

Published Aug 12, 2026 · Updated Aug 12, 2026

SSRF in the FortiSIEM GUI in releases 6.4.1 through 7.5.0 allows remote authenticated users to issue appliance-originated requests. The GUI processes specially crafted HTTP requests by causing the appliance to send attacker-directed HTTP requests; Fortinet has not disclosed the affected handler or exact validation failure. High privileges over the network are required, and resulting requests can reach resources available to the appliance without reported service interruption.
