Summary
The PuppyFW WordPress plugin through 0.4.4 does not have proper authorisation on one of its REST routes, which tests the caller against a capability taken from the request itself, allowing any authenticated user, including subscribers, to add, modify and delete arbitrary blog options and thereby escalate their privileges.
