Lifecycle detail
Mattermost 7.1 was released on July 13, 2022 and support ended on May 15, 2023 — a supported lifespan of 10 months, in line with the 9 months median for Mattermost LTS releases. It was a long-term support (LTS) release, so it received a longer patch window than the interim releases around it. The last patch it will ever receive is 7.1.9, published April 27, 2023 — 18 days before support ended. It has been without security patches for 3 years and 5 months. 39 newer Mattermost releases have shipped since.

What does Mattermost 7.1 end of life mean?
When Mattermost 7.1 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 Mattermost 7.1 past its EOL date creates a growing attack surface that a clean scan result does not rule out.
Migrate to Mattermost 11.7 or implement compensating controls — network segmentation, enhanced monitoring, restricted access — while migration is underway.
