# FortiManager: authenticated admin can escalate privileges to root via HTTP

Link for people: https://infrastack.ai/live/CVE-2026-126218 (this .md is for agents)

A flaw in Fortinet FortiManager 8.0.0 through 8.0.1, 7.6.0 through 7.6.7 and 7.4.0 through 7.4.11 lets a remote attacker who already has admin permission elevate their privileges to root. It is triggered by crafted HTTP requests.

_Summary, check and fix written by a model from the sources; labelled as such._

## Affected

- vendor:FortiManager affected >= 8.0.0, <= 8.0.1; >= 7.6.0, <= 7.6.7; >= 7.4.0, <= 7.4.11 fixed 8.0.2, 7.6.8, 7.4.12

## How to check

Run 'get system status' in the FortiManager CLI (or check System Settings > Dashboard in the GUI) and compare the version: affected are 8.0.0-8.0.1, 7.6.0-7.6.7, 7.4.0-7.4.11. Also review which accounts hold admin permission.

## Fix

Upgrade FortiManager 8.0.x to 8.0.2+, 7.6.x to 7.6.8+, 7.4.x to 7.4.12+. FortiManager 7.2 is not affected.

## Documents

- [advisory] FG-IR-26-235 FortiManager authorization bypass through user-controlled key https://fortiguard.fortinet.com/psirt/FG-IR-26-235

## From the sources

A authorization bypass through user-controlled key vulnerability in Fortinet FortiManager 8.0.0 through 8.0.1, FortiManager 7.6.0 through 7.6.7, FortiManager 7.4.0 through 7.4.11 may allow a remote authenticated attacker with admin permission to elevate their privileges to root via crafted HTTP requests.
