Description The "Editor" tab under the "Tables" section is vulnerable to stored XSS. It is possible to store XSS in all input fields as the code does not sanitize any of the user input. # 2. Proof of Concept (PoC) Enter the following payload into any input field: "><script>alert(1)</script><!--' The payload is stored in the document and executes whenever a user visits the "Settings" tab or the document itself. The document is also cached by the plugin. Therefore, the payload can also be executed by any unauthenticated user visting http://192.168.0.49/wp-content/uploads/supsystic-tables/cache/tables/[YOUR TABLE NUMBER]
