A Joomla! 3.7.1 release containing a security fix will be published on Wednesday 17th May at approximately 14:00 UTC.
The Joomla! Security Strike Team (JSST) has been informed of a critical security issue in the Joomla! core.
Since this is a very important security fix, please be prepared to update your Joomla! installations next Wednesday.
Until the release is out, please understand that we cannot provide any further information.
Please note: the upcoming release candidates of 3.7.1 this afternoon will not include the security fix.
