CVE-2016-9964
redirect() in bottle.py in bottle 0.12.10 doesn't filter a "\r\n" sequence, which leads to a CRLF attack, as demonstrated by a redirect("233\r\nSet-Cookie: name=salt") call.
Does this matter?
Lower severity and a low EPSS score (1.76%). Track it; it rarely justifies an emergency change on its own.
