The session id from the client's cookie reaches memcached unchanged as the cache key.
A CR and LF in the session id end the cache command early, and the server reads the bytes after them as further commands.

Vendor Solution
Upgrade to HTTP::Session 0.43 or later. Note that HTTP::Session 0.54 includes additional security fixes, but has been marked as deprecated. Users should migrate to an alternative such as Plack::Middleware::Session.
