Advisory
Source description from Wordfence Intelligence, credited to wesley (wcraft).
The LWSCache plugin for WordPress is vulnerable to unauthorized modification of data due to improper authorization on the lwscache_activatePlugin() function in all versions up to, and including, 2.8.5. This makes it possible for authenticated attackers, with Subscriber-level access and above, to activate arbitrary whitelisted LWS plugins.
