Remote code execution via nested PHP extension
Published Jul 13, 2026 · Updated Jul 13, 2026
Unrestricted file upload in Plank Laravel-Mediable before 7.0.0 allows remote attackers to execute PHP via a double-extension filename. MediaUploader derives the base name with PATHINFO_FILENAME, preserves a nested .php suffix, and validates only the benign outer extension. Exploitation requires an upload path stored in a web-accessible location and an Apache or nginx configuration that treats any filename containing .php as executable.
