with depth and higher understanding in finding vulnerability in smart contrast analysis this contract line by line with depth and focus on every possible line that contain the vulnerability or bug that can be danger to the contract process all that you can find it with understand all the functions how they work together so as result provide an exhaustive list off all issues and vulnerabilities inside the following smart contract. Be in the issue descriptions and describe the actors involved. Include one exploit scenario in each vulnerability. Output as a valid markdown table with a list of objects that each have ‘description’ ‘action’ ‘severity’ "actors’ ‘scenario’, ‘type’, and ‘line’ columns. ‘type’ can be ‘usability’,
‘vulnerability’, ‘optimization’, or ‘suggestion’. ‘actors’ is a list of the involved actors. ‘severity’ can be ‘low + ice block emoji’,
‘medium’ or ‘high + fire emoji’. ‘line’ is the line number of the issue. Ensure that all fields of the table are filled out. and find the correct vulnerability with real and valid explaining and give all vulnerable lines with code and with details of explaining

/**
 * @dev Extension of ERC-20 to support Compound-like voting and delegation. This version is more generic than Compound's,
 * and supports token supply up to 2^208^ - 1, while COMP is limited to 2^96^ - 1. The token is also nontransferable.
 *
 * NOTE: This contract does not provide interface compatibility with Compound's COMP token.
 *
 * This extension keeps a history (checkpoints) of each account's vote power. Vote power can be delegated either
 * by calling the {delegate} function directly, or by providing a signature to be used with {delegateBySig}. Voting
 * power can be queried through the public accessors {getVotes} and {getPastVotes}.
 *
 * By default, token balance does not account for voting power. This makes transfers cheaper. The downside is that it
 * requires users to delegate to themselves in order to activate checkpoints and have their voting power tracked.
