Authenticated arbitrary file read via unchecked AJAX path
Published Jan 2, 2023 · Updated Apr 10, 2025
Arbitrary file read in Welcart e-Commerce before 2.8.5 allows remote authenticated users to read server files through a WordPress AJAX action. The wel_check_progress_ajax handler uses the attacker-controlled progressfile value to return file contents without restricting the requested path. Subscriber-level access is sufficient, and exposed data is limited to files readable by the WordPress server process.
