CVSS 8.8 · High EPSS 0,84%
Kerentanan Unrestricted Upload of File with Dangerous Type. Skor CVSS 3.1 8.8 (High) menurut vulncheck.com.
The Grav API plugin (getgrav/grav-plugin-api) before 1.0.3 contains a file upload extension bypass in the API media controller. HandlesMediaUploads::validateFileExtension() inspects only the final file extension via pathinfo($filename, PATHINFO_EXTENSION), so a user with api.media.write permission can upload a file with a double extension such as shell.php.jpg to bypass the dangerous extensions blocklist. The web server may then execute the file as PHP, resulting in remote code execution.
