By omitting validation of EIP-2930 access lists in custom 0x76 transaction envelopes, the library allows malicious clients to pad transaction payloads with dummy addresses, draining the gas sponsor's hot wallet.\n\n## TL;DR\nUnvalidated access list padding allows attackers to drain native tokens from sponsored gas wallets on EVM-compatible networks.\n\n## Exploit Status: POC\n\n## Technical Details\n\n- **CWE ID**: CWE-400, CWE-20\n- **Attack Vector**: Network / Remote\n- **CVSS Score**: 7.5 (High)\n- **Impact**: Wallet Fund Depletion / Denial of Service\n- **Exploit Status**: Proof of Concept available\n\n## Affected Systems\n\n- ZenHive mpp (Multi-Payment Protocol) Elixir library\n- **mpp**: < 0.6.0 (Fixed in: `0.6.0`)\n\n## Mitigation\n\n- Upgrade ZenHive mpp library to v0.6.0 or higher\n- Temporarily disable transaction fee sponsorship in application configuration\n\n**Remediation Steps:**\n1. Update mix.exs with {:mpp, \"~> 0.6.0\"}\n2. Run mix deps.get and mix compile to pull the patched version\n3.
