PHP7 is vulnerable to NULL byte injection. While using get_headers() with user-supplied URL, if the URL contains null byte \0, the URL will be silently truncated. This causes certain software to make incorrect assumptions about the target of the get_headers() and potentially send confidential information to a wrong server.
