Freshness: upstream tracker timestamp is available; use API updated time as primary recency signal.
CVE-2016-9964 medium priority: Ubuntu including 1 source packages (python-bottle), 16 status rows across 16 suites (artful, bionic, cosmic, disco, eoan, focal, groovy, hirsute, impish, jammy, precise, trusty, upstream, xenial, yakkety, zesty): not-affected 11, released 4, ignored 1.
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.
