CVE-2026-59694
Improper Validation of Specified Quantity in Input in ZenHive mpp allows an unauthenticated remote client to inflate the fee-payer's gas cost per payment by a large multiplier, degrading the sponsor's operating margin. When the mpp Elixir library is configured as fee payer feepayer: true,...

On the Consideration of Vanity Address Generation Via Identity-Based Signatures
An address is indicated as an identifier of the user on the blockchain, and is defined by a hash value of the ECDSA verification key. A vanity address is an address that embeds custom characters such as a name. To generate a vanity address, a classical try-and-error method is employed, and thus t...
A Smart Contract-Based Non-Transferable Signature Verification System Using Nominative Signatures
Nominative signatures allow us to indicate who can verify a signature, and they can be employed to construct a non-transferable signature verification system that prevents the signature verification by a third party in unexpected situations. For example, this system can prevent IOU/loan certifica...
Users can avoid liquidation by splitting their positions into smaller ones
Lines of code Vulnerability details Impact Bad debt creation, as the total sum of positions could yield a signicant underwater position, but they would likely not be liquidated as it wouldn't compensate liquidators. Proof of Concept A recent, random transaction on Mantle shows a gas fee of 0.47...
Potential Gas Inefficiency due to Unnecessary abi.encode Usage
Lines of code Vulnerability details Impact The function unnecessarily uses abi.encode to convert a uint256 to bytes32, incurring additional gas costs. This doesn't affect correctness but may lead to suboptimal gas usage. Proof of Concept By modifying the fetchInteractionId function to directly ca...
High possibility of DOS
Lines of code Vulnerability details Impact In the claimAuction function there is a high possibility of DOS where the auction winner is unable to claim the NFT due to high gas cost or not enough gas, this is due to the functions having three loops on same array of all bids, they are in the...
A whale can DoS the token service by reaching flowlimit
Lines of code Vulnerability details Impact Clients can't transfer tokens between chains because the flow limit is reached. Proof of Concept In FlowLimit.sol:addFlow, we revert if current flowToAdd + flowAmount flowToCompare + flowLimit: uint256 flowToAdd; uint256 flowToCompare; assembly flowToAdd...
Loss of user funds due to gas Limit set to zero on L2StandardBridge
Lines of code Vulnerability details Impact User loss of funds in the event a deposit fails. Proof of Concept In L2StandardBridge.finalizeDeposit, there exists an issue related to the gas limit setting. In the event of a failed transfer, it attempts to create a return transaction to refund the use...
Equity.restructureCapTable only restructures one address at a time
Lines of code Vulnerability details Equity.restructureCapTable allows qualified FPS holders to restructure the system, that is: burning shares of other holders that did not participate in putting equity above water. File: Equity.sol 309: function restructureCapTableaddress calldata helpers, addre...
CVE-2023-28431
Frontier is an Ethereum compatibility layer for Substrate. Frontier's modexp precompile uses num-bigint crate under the hood. In the implementation prior to pull request 1017, the cases for modulus being even and modulus being odd are treated separately. Odd modulus uses the fast Montgomery...

CVE-2023-28431
CVE-2023-28431 describes a vulnerability in Frontier’s modexp precompile used by Substrate. The implementation treats even and odd moduli differently: odd moduli use Montgomery multiplication, while even moduli fall back to a slower plain power algorithm. This mismatch caused a gas-cost discrepan...
