Affected versions of this package are vulnerable to Deserialization of Untrusted Data via the MemCacheStore and RedisCacheStore. when untrusted user input is written to the cache store using the raw: true parameter, re-reading the result from the cache can evaluate the user input as a Marshalled object instead of plain text.
