## Fortinet FortiManager: critical vulnerability
Severity: critical. Patch status: partial fix.
Affected: Fortinet FortiManager
Fixed in: FortiAnalyzer 7.6.8, FortiAnalyzer Cloud 7.6.8, FortiManager 7.6.8, FortiManager Cloud 7.6.8, FortiAnalyzer-BigData 7.6.8
Ids: CVE-2026-126170

A improper encoding or escaping of output vulnerability in Fortinet FortiAnalyzer 8.0.0 through 8.0.2, FortiAnalyzer 7.6.0 through 7.6.7, FortiAnalyzer Cloud 8.0.1 through 8.0.2, FortiAnalyzer Cloud 7.6.0 through 7.6.7, FortiAnalyzer-BigData 7.6.0 through 7.6.2, FortiManager 8.0.0 through 8.0.2, FortiManager 7.6.0 through 7.6.7,…

## Steps
1. This touches infrastructure (vpn-edge). Look in terraform, ansible, cloud-init, Dockerfiles and docs for the product and version we run. If it isn't in the repo, say so and list what a human should check on the box.
2. Fix by release line: FortiAnalyzer: 7.6.x → 7.6.8. FortiAnalyzer Cloud: 7.6.x → 7.6.8. FortiManager: 7.6.x → 7.6.8. FortiManager Cloud: 7.6.x → 7.6.8. FortiAnalyzer-BigData: 7.6.x → 7.6.8. No fix yet on FortiAnalyzer 8.0.x; FortiAnalyzer Cloud 8.0.x; FortiManager 8.0.x; FortiManager Cloud 8.0.x. Until one ships: restrict network access to it.

## Fix by release line
| Line | State | Fix | Until then |
|---|---|---|---|
| FortiAnalyzer 8.0.x | no fix yet | — | restrict network access to it |
| FortiAnalyzer 7.6.x | fixed | 7.6.8 | — |
| FortiAnalyzer Cloud 8.0.x | no fix yet | — | restrict network access to it |
| FortiAnalyzer Cloud 7.6.x | fixed | 7.6.8 | — |
| FortiManager 8.0.x | no fix yet | — | restrict network access to it |
| FortiManager 7.6.x | fixed | 7.6.8 | — |
