Json Options
Monthly
Full site takeover in the JSON Options WordPress plugin (versions through 0.0.4) is possible because one of its actions runs on every request without any capability check or nonce verification, exposing arbitrary WordPress option updates to unauthenticated users. An attacker can flip the users_can_register option on and set default_role to administrator, then self-register an admin account. Publicly available exploit code exists (reported by WPScan), and the flaw is rated CVSS 9.8 with SSVC technical impact assessed as total.
