# Wegow: ticket sales PDF export lets promoters forge server-side requests

The Wegow ticket sales chart PDF export accepts an attacker-controlled svg parameter that is sent to the export.highcharts.com service, which fetches external URLs and embeds the responses in the PDF. An authenticated promoter can use the export service as a proxy to reach attacker-chosen resources.

_Summary, check and fix written by a model from the sources; labelled as such._

## Affected

- vendor:Wegow affected unknown (vendor says only actual version) fixed ?

## How to check

No customer-side check: this is a vendor-hosted feature. Wegow operators could look for POST requests from the PDF download whose svg parameter contains external URLs (href/xlink:href/image references) and review which promoter accounts sent them.

## Fix

unknown: INCIBE says no solution reported as of 2026-10-16; no fixed version published. Ask Wegow support; restrict promoter accounts meanwhile.

## From the sources

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.
