Rules: work read-only. Do not run exploit code, proof-of-concept scripts or scanners that send attack payloads, and do not change any configuration, package, image or deployment. Report findings only. What cve.now has for CVE-2026-126224 (entry last updated 2026-11-11): Affected: - Fortinet FortiManager: from 7.6.0, through 7.6.7; from 7.4.0, through 7.4.11; from 7.2.0, through 7.2.12 - Fortinet FortiAnalyzer: from 7.6.0, through 7.6.7; from 7.4.0, through 7.4.11; from 7.2.0, through 7.2.12 - Fortinet FortiAnalyzer Cloud: from 7.6.0, through 7.6.7; from 7.4.1, through 7.4.11; from 7.2.1, through 7.2.12 - Fortinet FortiManager Cloud: from 7.6.0, through 7.6.7; from 7.4.1, through 7.4.11; from 7.2.1, through 7.2.12 Fixed versions: 8.0.1. 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-2026-126224 is not listed as of cve.now's last read. This KEV status is for CVE-2026-126224 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-26-239 - https://www.cve.org/CVERecord?id=CVE-2026-126224 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. Entry: https://cve.now/CVE-2026-126224 For follow-up questions, use the cve.now MCP server at https://mcp.cve.now/mcp (no authentication), for example execute with name cve.get and arguments {"id": "CVE-2026-126224"}. ``` ## FAQ ### Is CVE-2026-126224 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-2026-126224 ### What does this mean? The bug lets an authenticated, privileged admin user run code or commands they are not authorized to run. The fact sheet says it may allow this through improper handling of argument delimiters in a command (argument injection). Source: https://fortiguard.fortinet.com/psirt/FG-IR-26-239, https://www.cve.org/CVERecord?id=CVE-2026-126224 ### Which versions are affected by CVE-2026-126224? FortiManager: from 7.6.0 through 7.6.7; from 7.4.0 through 7.4.11; from 7.2.0 through 7.2.12. FortiAnalyzer: from 7.6.0 through 7.6.7; from 7.4.0 through 7.4.11; from 7.2.0 through 7.2.12. FortiAnalyzer Cloud: from 7.6.0 through 7.6.7; from 7.4.1 through 7.4.11; from 7.2.1 through 7.2.12. FortiManager Cloud: from 7.6.0 through 7.6.7; from 7.4.1 through 7.4.11; from 7.2.1 through 7.2.12. Source: https://cve.now/CVE-2026-126224 ### Am I affected, and how do I check? The checked ranges cover FortiManager, FortiAnalyzer, FortiAnalyzer Cloud, and FortiManager Cloud: 7.2.0 through 7.2.12, 7.4.0 through 7.4.11, and 7.6.0 through 7.6.7, with the cloud variants starting at 7.2.1 and 7.4.1. Compare your installed version, shown in the device's system dashboard or with the get system status command, against these ranges. The checked facts do not list the 8.0.0 release named in the advisory header, so confirm that version against the vendor advisory. Source: https://fortiguard.fortinet.com/psirt/FG-IR-26-239, https://www.cve.org/CVERecord?id=CVE-2026-126224 ### How do I fix CVE-2026-126224? The checked fix is to upgrade FortiManager to version 8.0.1 or later. The facts do not give a FortiAnalyzer-specific fixed version, so check the vendor advisory for the correct upgrade target for FortiAnalyzer.
