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 (entries disclosed well before this release train shipped are left out). 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.

FortiSandbox 3.1 Release Lifecycle

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.

This product has reached end of life as of , meaning Fortinet no longer provides technical support, software updates, or hardware replacement for this product.
