NVD description

InvenTree is an Open Source Inventory Management System. Prior to 1.4.0, privileged staff users who can author report or label templates can cause WeasyPrint report rendering to retrieve attacker-selected resources through the HTTP and HTTPS URL schemes or the local file URI scheme. The HTML(string=html).write_pdf() path does not provide a restricted url_fetcher, and attach_to_model=True stores the original generated PDF before later processing, allowing fetched local files or internal HTTP response bodies to be recovered from embedded attachments. This enables full-read server-side request forgery, arbitrary local file disclosure including application credentials, and possible compromise of a superuser account. This issue is fixed in version 1.4.0.
