The Freemius SDK, as used by hundreds of WordPress plugin and theme developers, was vulnerable to Cross-Site Request Forgery and Information disclosure due to missing capability checks and nonce protection on the _get_debug_log, _get_db_option, and the _set_db_option functions in versions up to, and including 2.4.2. Any WordPress plugin or theme running a version of Freemius less than 2.4.3 is vulnerable.

The transferProxy and approveProxy functions of a smart contract implementation for SmartMesh (SMT), an Ethereum ERC20 token, allow attackers to accomplish an unauthorized transfer of digital assets because replay attacks can occur with the same-named functions (with the same signatures) in other tokens: First (FST), GG Token (GG), M2C Mesh Network (MTC), M2C Mesh Network (mesh), and UG Token (UGT).
