This makes it possible for authenticated attackers, with subscriber-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. The missing current_user_can() check in the Factory framework\u0027s connect() dispatcher allows Subscriber-level users to bypass the manage_options capability gate and both harvest a valid wis_edit_feed nonce and overwrite any feed\u0027s slidespeed setting, after which the stored payload fires on every public pageview embedding the feed shortcode."
