CWE-616: Incomplete Identification of Uploaded File Variables (PHP)

"The PHP application uses an old method for processing uploaded files by referencing the four global variables that are set for each file (e.g. $varname, $varname_size, $varname_name, $varname_type). These variables could be overwritten by attackers, causing the application to process unauthorized files." - Entry from the Common Weakness Enumeration For more info visit <a href="https://cwe.mitre.org/data/definitions/616.html" target="_blank" rel="noopener noreferrer">CWE-616</a>
