Submission Details
Severity:
Duplicate Pools can be created
Summary
In the createPool we have no check to ensure we do not create a pool similar to one that already exists
function createPool(Pool calldata pool_) public onlyOwner {
require(pool_.payoutStart > block.timestamp, "DS: invalid payout start value");
_validatePool(pool_);
pools.push(pool_);
emit PoolCreated(pools.length - 1, pool_);
}
Recommendations
Before pushing the newly created pool to the array consider checking that the pool does not already exist
// Check if a similar pool already exists
require(!_poolExists(pool_), "DS: pool already exists");
