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-2026-63627 mppx: Gas Draining with padding

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...

GHSA-9P8R-4XP4-GW5W Vyper's `_abi_decode` vulnerable to Memory Overflow

Summary If an excessively large value is specified as the starting index for an array in abidecode, it can cause the read position to overflow. This results in the decoding of values outside the intended array bounds, potentially leading to bugs in contracts that use arrays within abidecode. The...

Buffer Overflow

Vyper is vulnerable to Buffer Overflow Vulnerability. The vulnerability is due to the improper bounds check for slices because it does not account for the potential overflow of start + length when non-literal values are used. This issue can be exploited by an attacker to perform out of bounds...

Vyper is a pythonic Smart Contract Language for the ethereum virtual machine. In versions 0.3.10 and earlier, the bounds check for slices does not account for the ability for start + length to overflow when the values aren't literals. If a slice function uses a non-literal argument for the start ...
