File upload vulnerability in InvoicePlane through 1.6.3 allows authenticated attackers to upload arbitrary PHP files into attachments, which can later be executed remotely, leading to Remote Code Execution (RCE).
Weakness
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.
