SSRF in Inventree
CVE-2026-61749
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.
