The Cryptocurrency (Token), Launchpad (Presale), ICO & IDO, Airdrop by TokenICO plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the 'saveDeployedContract' function in all versions up to, and including, 2.4.6. This makes it possible for authenticated attackers, with Subscriber-level access and above, to overwrite the WordPress option tokenico_deployed_contracts, poisoning the smart contract addresses displayed.
