Description

Joomla Extension - regularlabs.com - various code injection vectors in Sourcerer extension - Free did not require both the article creator and last modifier to be Super Users before executing article PHP. Pro did not consistently enforce configured CSS, JavaScript and PHP permissions across tags, attributes, files and both article owners. PHP include attributes could also escape the configured include folder, and executable script/style variants could bypass detection.
