CVE-2022-38916Public exploitNetwork attack vector

Remote code execution via filename-tampered PHP upload

Published Sep 20, 2022 · Updated May 27, 2025

Unrestricted file upload in Pagekit 1.0.18 allows remote attackers to upload executable PHP files through the storage feature. The upload handler accepts a filename altered in transit to bypass the configured PHP-file restriction and writes it beneath /storage. No authentication or user interaction is required, and requesting the stored PHP file allows server-side code execution.
