Still on MySQL 5.7 or 8.0? Those high-severity CVE fixes are covered

Upstream MySQL published an out-of-schedule release this week with two high-severity CVE fixes. If you’re running Percona Server for MySQL 5.7 or 8.0 under Extended Lifecycle Support (ELS), the program we previously called Post EOL Support, you don’t have to do anything to qualify for them. We’ve already applied the fixes and re-released the affected ELS builds.

This is the point of ELS. When a major version reaches End of Life (EOL), the community stops shipping patches, but the databases running on it don’t stop mattering. ELS keeps critical bug and security fixes coming for versions that are past their EOL date, so you can stay on 5.7 or 8.0 on your own timeline instead of a deadline someone else set.

What we did

These CVE fixes landed upstream outside the normal cadence. Under ELS, customers are entitled to security fixes for the versions they run, so we pulled the patches into the 5.7 and 8.0 builds and re-released them. ELS customers will get access to the updated builds from the usual private repository in the next couple of weeks.

Why this matters if you’re still on 5.7 or 8.0

Percona Server for MySQL 5.7 reached EOL in October 2023. Percona Server for MySQL 8.0 reached EOL in April 2026. Plenty of production systems are still on both, and not every migration can happen on the upstream’s schedule. Running an unpatched database past EOL is where the real risk sits: no security fixes, no bug fixes, and no support when something breaks at 2:00 a.m.

ELS closes that gap. You keep getting the critical fixes, including out-of-schedule security patches like these, while you plan an upgrade on terms that work for your team.

Where to go from here

If you’re on 5.7 or 8.0 and don’t have ELS in place, now is a good time to look at it. The fixes we just shipped are exactly what the program is for. See the details for your version: Extended Lifecycle Support for MySQL 8.0 or Extended Lifecycle Support for MySQL 5.7. Or reach out via percona.com or the Percona Community Forum to discuss coverage for your environment.
