mpp vulnerable to Gas Draining with low gas limit

Vulnerability When the server acts as the fee payer, mpp Elixir 0.4.0 ZenHive/mpp does not validate whether the gaslimit set by the client is enough before broadcasting. A malicious client can drain the server's gas without paying. A transferWithMemo call on Tempo Moderato testnet requires 51,299...

mpp vulnerable to Gas Draining with access list

Details When the server acts as the feepayer, mpp Elixir 0.4.0 copies the client-supplied EIP-2930 access list verbatim into the cosigned fee-payer transaction. In cosignfeepayer, the server re-signs the raw basefields index 5 of the 0x76 AASigned envelope without inspecting the access list field...

GHSA-VV77-66RF-PM86 mpp vulnerable to Gas Draining with no limit

Details When the server acts as the feepayer, the mpp Elixir 0.4.0 does not validate gaslimit, maxfeepergas and maxpriorityfeepergas before cosigning the client's fee-payer transaction. A malicious client embeds arbitrarily large maxfeepergas and maxpriorityfeepergas values in the signed envelope...

mppx: Gas Draining with access list

Details When the server acts as the feepayer, mppx 0.6.27 copies the client-supplied EIP-2930 access list verbatim into the cosigned fee-payer transaction. The TypeScript SDK's fee-payer cosigning path accepts any accesslist the client includes in the 0x78 FeePayerEnvelope without inspecting its...

mppx: Gas Draining with padding

Details When the server acts as the feepayer, mppx 0.6.27 validates calldata using viem's decodeFunctionData, which is lenient about trailing bytes. The FeePayerPolicy caps gaslimit ≤ 2 M and maxfeepergas ≤ 100 Gwei but does not check calldata length. Tempo uses legacy calldata gas pricing: 16 ga...

CVE-2026-63628

mppx is a TypeScript interface for machine payments protocol. Prior to 0.8.2, the fee-payer cosigning path in src/tempo/internal/fee-payer.ts copied a client-supplied accesslist from a 0x78 FeePayerEnvelope without validating its length or contents. Because EIP-2930 access-list entries consume...

CVE-2026-63627

mppx is a TypeScript interface for machine payments protocol. Prior to 0.8.2, FeePayerPolicy in src/tempo/internal/fee-payer.ts used decodeFunctionData to validate fee-sponsored calldata but did not reject trailing bytes. A client could append nonzero padding that increased intrinsic calldata gas...
