Anyone can complete the Rng relay auction

Lines of code Vulnerability details Impact There's no access restriction on rngComplete which allows anyone to execute this function and complete the auction. This can lead to unexpected behavior or potential DOS attack where a user completes the auction. Tools Used Manual Analysis Recommended...

Closing the draw will be compromised if the recipient reward is address(0)

Lines of code Vulnerability details Impact The rngComplete function receives the RNG request results, it closes the draw using the randomNumber generated by the RNG request auction and it transfer the rewards. The problem is that a malicious actor can introduce a address zero in the recipient...

function rngComplete is unpprotected

Lines of code Vulnerability details Impact The rngComplete is a function Called by the relayer to complete the Rng relay auction. However it has zero access control. Proof of Concept The function makes calls to the prizepool to close a draw, it also withdraws from a reserve. All these are done wi...
