Lifecycle detail
Unity 2018 was released on April 26, 2018 and support ended on June 17, 2021 — a supported lifespan of 3 years and 2 months, in line with the 2 years and 10 months median for Unity LTS releases. It was a long-term support (LTS) release, so it received a longer patch window than the interim releases around it. Its latest release on record is 2018.4.36f1, published June 17, 2021 — on the day support ended. It has been past its end-of-life date for 5 years and 5 months. 15 newer Unity releases have shipped since.

What does Unity 2018 end of life mean?
When Unity 2018 reaches end of life, the maintainers stop issuing security patches for this version. CVEs discovered after the EOL date are publicly disclosed on the National Vulnerability Database with no patch available. Exploit code frequently appears on GitHub within days of disclosure.
The CVE blind spot: A CVE-based scan does not show the ongoing accumulation of unpatched vulnerabilities in EOL software versions. Some scanners flag unsupported versions of common products, but coverage varies, and none of them give you the date in advance. Running Unity 2018 past its EOL date creates a growing attack surface that a clean scan result does not rule out.
Migrate to Unity 6.6 or implement compensating controls — network segmentation, enhanced monitoring, restricted access — while migration is underway.

What are the security risks of running Unity 2018 past EOL?
Since Unity 2018 reached end of life, the maintainers no longer issue security patches. Any CVEs disclosed after the EOL date accumulate with no vendor fix. A CVE-based scan does not show this — it is the CVE blind spot; some scanners flag unsupported versions of common products, but coverage varies and none give the date in advance. Organizations running EOL Unity should migrate immediately or implement compensating controls.
