## Technical details

The vulnerability exists in the Freemius SDK's purchase-completion handler, which processes the 'purchased_plan' request parameter without input sanitization or output escaping. It stores unsanitized input in a persistent, site-wide administrative notice that executes for any authenticated user with subscriber or higher privileges, with no nonce or capability checks required. The attack requires prior authentication and the site's Freemius opt-in to be active (the default state after an admin clicks "Allow & Continue").
