Official description
Server-Side Request Forgery (SSRF) reported in the ticket sales chart PDF export functionality of Wegow. According to the report, an authenticated user with a promoter account can manipulate the <svg> parameter of the POST request generated by selecting Download PDF. The content is processed by the export.highcharts.com service, which sends HTTP requests to attacker-controlled external resources and embeds their responses in the generated PDF. The reported behavior allows the export service to be used as an intermediary for these requests.
