Summary

Server-Side Request Forgery (SSRF) is reported in the ticket sales chart PDF export functionality of Wegow. An authenticated user with a promoter account can manipulate the <svg> parameter of the POST request generated by selecting Download PDF, causing the export.highcharts.com service to send HTTP requests to attacker-controlled external resources and embed their responses in the generated PDF.

Risk Assessment

An attacker can use the export service as an intermediary to send requests to internal or external resources, potentially leading to information disclosure or other attacks. This may also allow bypassing network security controls.

Recommendation

Restrict manipulation of the <svg> parameter through input validation and prevent references to external resources. Consider updating or configuring the export service to block unauthorized requests.
