Abstract
------------------------------------------------------------------------
A persistent Cross-Site Scripting (XSS) vulnerability has been found in
the WooCommerce WordPress Plugin (millions of active installations). An
attacker can create a specially crafted image file which, when uploaded
as a product image in WordPress, injects malicious JavaScript code into
the application. An attacker can use this vulnerability to perform a
wide variety of actions, such as stealing victims' session tokens or
login credentials, and performing arbitrary actions on their behalf.
