Os Release
· FortiOS Series
Is FortiOS 7.0 still maintained?
No. Fortinet no longer maintains FortiOS 7.0; support ended 2025-09-30. 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 7.0 stop?
Engineering fixes for FortiOS 7.0 — including security patches — stop on 2024-03-30. 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 7.0 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 7.0 past end of support?
7 CVEs in CISA's Known Exploited Vulnerabilities catalog affect Fortinet FortiOS. Because FortiOS 7.0 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. 7 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 7.0 Release Lifecycle
FortiOS 7.0 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 7.0 should plan a migration .
