جزئیات آسیب‌پذیری

The Flex QR Code Generator plugin for WordPress is vulnerable to arbitrary file uploads due to missing file type validation in thesave_qr_code_to_db() function in all versions up to, and including, 1.2.5. This makes it possible for unauthenticated attackers to upload arbitrary files on the affected site's server which may make remote code execution possible.
