+Subject: [PATCH 1/2] Fix #77423: parse_url() will deliver a wrong host to user
+
+To avoid that `parse_url()` returns an erroneous host, which would be
+valid for `FILTER_VALIDATE_URL`, we make sure that only userinfo which
+is valid according to RFC 3986 is treated as such.
+
+For consistency with the existing url parsing code, we use ctype
+functions, although that is not necessarily correct.
+
