CVE-2026-84063Network attack vector

Authenticated PHP execution via unrestricted file upload

Published Sep 10, 2026 · Updated Sep 10, 2026

Unrestricted file upload in D-ZERO BurgerEditor 2.28.0 through 2.30.0 and 3.2.0 through 3.4.0 allows remote authenticated users to execute PHP. When Bge.allowedAdmin is enabled, upload handling accepts server-executable extensions and saves the files in a publicly accessible directory. The attacker needs a product login with high privileges, and requesting the saved file URL without authentication executes its PHP code.
