Question 1

Question 2

Is NGINX 1.15 still supported?

Accepted Answer

NGINX 1.15 is no longer supported — it has passed its end of life date (May 21, 2019). No further security patches will be issued. Upgrade to a supported version or obtain extended lifecycle support.

Question 3

When does NGINX 1.15 reach end of life?

Accepted Answer

NGINX 1.15 reached (or will reach) end of life on May 21, 2019. After this date, no security patches or bug fixes are issued by the vendor.

Question 4

What are the security risks of running NGINX 1.15 after end of life?

Accepted Answer

After end of life, the vendor's standard support for NGINX 1.15 ends, so newly discovered vulnerabilities may never be fixed unless a paid extended support option covers that version. Auditors ask about it too: PCI DSS requirement 12.3.4, for example, calls for a yearly review of vendor end-of-life announcements with a remediation plan approved by senior management.
