CVE-2020-13254: Potential data leakage via malformed memcached keys
In cases where a memcached backend does not perform key validation, passing malformed cache keys could result in a key collision, and potential data leakage. In order to avoid this vulnerability, key validation is added to the memcached cache backends.
Thank you to Dan Palmer for the report and patch.
