CVE-2024-8538Network attack vector

Full-path disclosure via unsanitized upload error

Published Sep 7, 2024 · Updated Apr 8, 2026

Full-path disclosure in Infinite Uploads Big File Uploads 2.1.2 and earlier allows remote authenticated users to read the web root path. The chunked-upload handler embeds its server-side file path in a client-visible error response instead of replacing it with a generic message. Author-level upload access is required, and the disclosed path only assists follow-on attacks that exploit another flaw.
