The Quote Comments plugin for WordPress is vulnerable to Missing Authorization in all versions up to, and including, 3.0.0. This is due to missing authorization checks in the quotecomments_add_admin function. This makes it possible for authenticated attackers, with Subscriber-level access and above, to update arbitrary plugin options via the 'action' parameter.
