A few days ago, a critical vulnerability in the Joomla! core was found. It comes from an unsanitized input in the Joomla! core, which makes an SQL injection possible. The result of such an attack can lead to totally compromised websites - stolen login details, hijacking website access, malicious file uploads, etc. It’s a serious threat, without a doubt, and one that applies to all Joomla! 3.2 versions and above.
