CVE-2026-126229 is not in CISA's Known Exploited Vulnerabilities (KEV) catalog. No public exploit code is tracked. It is rated CVSS 9.1 (critical) and affects FortiManager, FortiAnalyzer, FortiManager Cloud and 1 more; no fixed version is listed; see the vendor advisory.

## Summary

Fortinet FortiAnalyzer, FortiManager, and their Cloud versions have an authorization bypass flaw that lets a logged-in administrator reach other virtual domains (VDOMs) they should not have access to. The attacker can exploit it remotely over the network by sending specially crafted HTTP requests, but needs high-privilege administrator login access first.

Model-written summary (anthropic/claude-sonnet-5.5). Verify details against the original sources.

## Who should check

Teams running Fortinet FortiManager or FortiAnalyzer, including Cloud editions, on 7.0–8.0.1 with multiple VDOMs; 7.0 and 7.2 need migration to a fixed release.

Conditions (all must be true for the bug to be hit):
- Running an affected FortiManager, FortiAnalyzer, FortiManager Cloud or FortiAnalyzer Cloud version (7.0 and 7.2 all versions, 7.4.0–7.4.11, 7.6.0–7.6.7, 8.0.0–8.0.1) (source: https://fortiguard.fortinet.com/psirt/FG-IR-26-244)
- Attacker is an authenticated administrator sending specially crafted HTTP requests (source: https://fortiguard.fortinet.com/psirt/FG-IR-26-244)
Setup: unknown whether the bug needs a non-default feature or setting. Check the advisory.
Attacker needs: network access, high-privilege login, no user action.
CISA KEV: CVE-2026-126229 is not listed as of cve.now's last read.
This KEV status is for CVE-2026-126229 only. If you also check another CVE, look up its own KEV status; never assume it from this one.

How to check:
- Installed software: check what is actually running, not what a repo declares. Read the version from each host, container image and Kubernetes node (the binary's version output, the OS package database, image layers), and check whether the conditions above hold there. Distribution packages may carry a backported fix under an older version number; confirm against the distribution's own advisory.

Verify against the linked advisories before concluding, and cite the date you read each one:
- https://fortiguard.fortinet.com/psirt/FG-IR-26-244
Do not conclude an asset is unaffected unless you checked it and the evidence covers both its version and the conditions above. If you could not check something, mark it unknown and say what is missing.

Report a table with one row per asset and these columns: Asset | Version or build | Status (affected, fixed, not applicable, unknown) | Compensating controls | Exposure (internet-facing, internal, none) | Evidence | Next action.

## FAQ

### Is CVE-2026-126229 being exploited?

It is not in CISA's Known Exploited Vulnerabilities catalog, and CISA's SSVC assessment does not mark exploitation as active. That does not mean it has not been attacked: vendors and researchers can report attacks before CISA lists them. No public exploit code is tracked.

Source: https://cve.now/CVE-2026-126229

### What does this mean?

An authorization bypass lets an authenticated administrator use specially crafted HTTP requests to access other VDOMs, going beyond the access they were meant to have.
