CVE-2024-9849Network attack vector

Authenticated arbitrary file upload via unchecked thumbnail

Published Nov 16, 2024 · Updated Apr 8, 2026

Unrestricted file upload in Real3D Flipbook Lite 4.8 and earlier allows remote authenticated users to place arbitrary files on the site server. The r3dfb_save_thumbnail_callback function accepts thumbnail content and writes it to server storage without validating the file type. Author-level WordPress access is required; uploaded executable content runs remotely only when the web server processes its type as code.
