The AMP for WP – Accelerated Mobile Pages plugin for WordPress is vulnerable to Arbitrary File Write in versions up to and including 1.1.12. This is due to unsafe ZIP file extraction in the ampforwp_save_local_font() function combined with inadequate cleanup that fails to remove nested directories and files. This makes it possible for authenticated attackers, with Author-level access and above, and permissions granted by an Administrator, to write arbitrary files to the server in a web-accessible location, potentially leading to remote code execution on hosts that execute PHP files in the uploads directory.
