Martin Cuddy from Radically Open Security has found a security issue concerning the generation of PDF files during a security audit conducted as a part of our NGI0 Entrust grant. Unauthenticated users were able to access all PDF files generated in the last 24 hours. This was possible by triggering the generation of a PDF file, determining its ID in the GraphQL request, and counting the ID upwards or downwards to access other PDF files.
