Overview

drogonframework/drogon is a C++14/17-based HTTP application framework.

Affected versions of this package are vulnerable to Arbitrary File Write. The unsafe handling of file names during upload using HttpFile::save() method may enable attackers to write files to arbitrary locations outside the designated target folder.
