Check your systems with an agent

Paste this into a coding or ops agent. It checks your systems read-only and reports a table per asset.

Check whether my systems are affected by CVE-2026-126179 (A improper neutralization of special elements used in an os command ('os command injection') vulnerability in Fortinet FortiAnalyzer…), using the cve.now data below.

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-2026-126179 (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
Fixed versions: 8.0.1.
Conditions (all must be true for the bug to be hit):
- Affected FortiManager, FortiManager Cloud, FortiAnalyzer and FortiAnalyzer Cloud builds in the listed version ranges (for example 7.2.0 through 7.2.12). (source: https://fortiguard.fortinet.com/psirt/FG-IR-26-224)
- Attacker must be an authenticated administrator. (source: https://fortiguard.fortinet.com/psirt/FG-IR-26-224)

Attacker needs: network access, high-privilege login, no user action.
CISA KEV: CVE-2026-126179 is not listed as of cve.now's last read.
This KEV status is for CVE-2026-126179 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-26-224
- https://www.cve.org/CVERecord?id=CVE-2026-126179
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.

Questions about CVE-2026-126179

Is CVE-2026-126179 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: cve.now feed data

What does this mean?

The flaw is an OS command injection, where special characters are not properly neutralized before being passed to the operating system. An authenticated administrator can use it to execute unauthorized code or commands on the affected appliance.Source: fortiguard.fortinet.com, cve.org

Which versions are affected by CVE-2026-126179?

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. 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.
