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-2026-126232 (A improper certificate validation vulnerability in Fortinet FortiAnalyzer 8.0.0 through 8.0.1, FortiAnalyzer 7.6.0 through 7.6.7…), 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-2026-126232 (entry last updated 2026-11-11):

Attacker needs: adjacent access, no login, no user action.
CISA KEV: CVE-2026-126232 is not listed as of cve.now's last read.
This KEV status is for CVE-2026-126232 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-26-247
- https://www.cve.org/CVERecord?id=CVE-2026-126232
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-2026-126232
Is CVE-2026-126232 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?
A man-in-the-middle attacker may be able to impersonate the RADIUS server by running a rogue RADIUS server, because the certificate is not properly validated.Source: fortiguard.fortinet.com, cve.org
Which versions are affected by CVE-2026-126232?
FortiManager: from 8.0.0 through 8.0.1; from 7.6.0 through 7.6.7; from 7.4.0 through 7.4.11; from 7.2.0 through 7.2.13. FortiAnalyzer: from 8.0.0 through 8.0.1; from 7.6.0 through 7.6.7; from 7.4.0 through 7.4.11; from 7.2.0 through 7.2.13. FortiAnalyzer Cloud: from 7.6.0 through 7.6.7; from 7.4.1 through 7.4.11; from 7.2.1 through 7.2.13. FortiManager Cloud: from 7.6.0 through 7.6.7; from 7.4.1 through 7.4.11; from 7.2.1 through 7.2.13.Source: cve.now feed data
