Descriptions

In the Simple 301 Redirects by BetterLinks WordPress plugin before 2.0.4, a lack of capability checks and insufficient nonce check on the AJAX action, simple301redirects/admin/activate_plugin, made it possible for authenticated users to activate arbitrary plugins installed on vulnerable sites.
