I tried it with a bit complex pdf structure and it worked like charm +1. Would love to learn more about the underlying techniques/tech.

  It just calls https://github.com/pdf2htmlEX/pdf2htmlEX https://github.com/pdf2htmlEX/pdf2htmlEX on the server.

    What calls what?

    You could create a file named ; echo 'hi'; # and it appears as if it would probably run anything you put between ; and # (in this case it will echo hi). Unless the filename is sanitized, which it appears to not be.

    Yeah. Switch array & args disable the shell. I hope they’re not running that locally as the download script suggests. But then you still have a bunch of other security issues. Shrug.

    I'm investigating the same. The upload endpoint uses secure_filename to get the filename used in that func. I'm not familiar with it, but the docs say it could return an empty string.

  Hey, there's nothing complex going on. I'm using a tool to convert pdf to html, and it does a phenomenal job.
