CVE-2026-39362Network attack vector

Authenticated SSRF via unchecked remote image URLs

Published Apr 8, 2026 · Updated Apr 8, 2026

SSRF in InvenTree before 1.2.7 allows remote authenticated users to access internal services through remote image URLs. The download_image_from_url function applies only Django URLValidator before requests.get follows redirects, without rejecting private, loopback, link-local, or reserved destinations. The opt-in INVENTREE_DOWNLOAD_FROM_URL setting must be enabled; successful requests can reach internal services or cloud metadata from the server.
