There is a serious security issue with OPcache, when being used in a shared hosting environment. This issue has been mitigated recently in a newer version of php. I'd like to request a backport for this fix. Upstream bug report, including patches: https://bugs.php.net/bug.php?id=69090 Thank you.
Notice: shared hosting is NEVER secure.
