## Known vulnerabilities

Portable UTF-8 versions prior to 5.4.26 (released 2019-11-05) have an open redirect vulnerability. The `Bootup::filterRequestUri()` method used an insecure `header('Location ...` implementation. And because it's most secure to not use this method at all, I decided to disable the function by default.
