ShareThis Dashboard for Google Analytics < 2.5.2 - Reflected Cross-Site Scripting (XSS)

The plugin does not sanitise or escape the ‘ga_action’ parameter in the stats view before outputting it back in an attribute when the plugin is connected to a Google Analytics account, leading to a reflected Cross-Site Scripting issue which will be executed in the context of a logged in administrator

PoC

Plugin needs to be connected to Google Analytics account. https://example.com/wp-admin/admin.php?page=googleanalytics&amp;ga;_action="><img+src%3Dx+onerror%3Dalert(document.domain)>
