What you said is definitely true. But in my system the videos are resized and converted into RAW format which I then extract color information from at different pixel locations, so it wouldn't really matter if it's an exe file or something else - it's only going to extract the binary data as color information to be used in other ways, and the converted files are never served. I doubt there's too much risk involved with my project using it in this way, but in other projects I'm sure it could be a security risk.

Yep, definitely didn't mean to imply that your project in specific was vulnerable, just wanted to give more of a general heads up for anyone else looking to do the same thing.
