Authenticated code execution via configurable PHP uploads
Published Sep 8, 2025 · Updated Sep 9, 2025
Arbitrary code execution in Maho before 25.9.0 allows remote authenticated users to execute PHP through product custom-option uploads. The custom-option editor accepts PHP in a staff-defined extension allowlist, writes the uploaded payload beneath the webroot at a predictable path, and executes it when requested. Access to Dashboard and Catalog Manage Products is required, but full administration is not; successful exploitation runs arbitrary PHP on the server.
