· FortiOS Series
Is FortiOS 6.0 still maintained?
No. Fortinet no longer maintains FortiOS 6.0; support ended 2022-09-29. It receives no fixes of any kind, including security patches. Devices running it are unpatched against any newer vulnerability — plan an upgrade to a maintained release. See Fortinet's lifecycle bulletin.
When do security fixes for FortiOS 6.0 stop?
Engineering fixes for FortiOS 6.0 — including security patches — stop on 2021-03-29. After that date, a device on this release cannot be patched against newly disclosed vulnerabilities without upgrading, which is the point that matters for KEV exposure and compliance.
What should I upgrade FortiOS 6.0 to?
Upgrade to a currently maintained Fortinet release. Check the release-train table on the vendor page for the nearest supported version.
What known-exploited CVEs apply to the FortiOS 6.0 past end of support?
12 CVEs in CISA's Known Exploited Vulnerabilities catalog affect Fortinet FortiOS. Because FortiOS 6.0 is past end of engineering, it will not receive fixes for them — a device left on this release is exploitable with no patch available. Upgrade to a maintained release. See the Known Exploited Vulnerabilities table below for the full list.
Known Exploited Vulnerabilities
This device is past Fortinet's security-support date. 12 CVEs in CISA's Known Exploited Vulnerabilities catalog apply to the platform it runs. Fortinet is not issuing patches for this model. Isolate, compensate, or refresh.

Source: CISA Known Exploited Vulnerabilities catalog. The Ransomware flag reflects CISA's own knownRansomwareCampaignUse field, set when the CVE has been observed in ransomware campaigns per their threat intel. It's not a property of the vulnerability description itself.
Correlation is at the platform level, not per-OS-version. Not exhaustive: KEV only lists actively-exploited CVEs and many relevant unexploited vulnerabilities are not here. Verify against vendor security advisories (PSIRT, JSA, PAN-SA) and NVD before acting. See compensating controls if refresh isn't immediate.
FortiOS 6.0 Release Lifecycle
FortiOS 6.0 is a Fortinet FortiOS software release. Releases are maintained on a fixed schedule: Fortinet ships fixes and security patches until the release reaches end of engineering, after which a device must be upgraded to a maintained release to stay patchable. The dates below are milestones for the software train, not for any specific appliance — hardware running this release has its own separate lifecycle. This product has reached end of life as of , meaning Fortinet no longer provides technical support, software updates, or hardware replacement for this product. Organizations still running the FortiOS 6.0 should plan a migration .
