CVE-2025-54429 Vulnerability Summary

CVE-2025-54429: Polkadot Frontier is an Ethereum and EVM compatibility layer for Polkadot and Substrate. There are various account address types in Frontier, e.g. precompiled contracts, smart contracts, and externally owned accounts. Some EVM mechanisms should be unreachable by certain types of accounts for safety. For precompiles to be callable by smart contracts they must be explicitly configured as CallableByContract. If this configuration is absent, then the precompile should be unreachable via smart contract accounts. In commits prior to 0822030, the underlying implementation of CallableByContract which returned the AddressType was incorrect. It considered the contract address running under CREATE or CREATE2 to be AddressType::EOA rather than correctly as AddressType::Contract. The issue only affects users who use custom precompile implementations that utilize AddressType::EOA and AddressType::Contract. It's not directly exploitable in any of the predefined precompiles in Frontier. This is fixed in version 0822030.

Assessing the Risk of CVE-2025-54429

Access Complexity Graph

The exploitability of CVE-2025-54429 depends on two key factors: attack complexity (the level of effort required to execute an exploit) and privileges required (the access level an attacker needs).

Exploitability Analysis for CVE-2025-54429

No exploitability data is available for CVE-2025-54429.

Understanding AC and PR

A lower complexity and fewer privilege requirements make exploitation easier. Security teams should evaluate these aspects to determine the urgency of mitigation strategies, such as patch management and access control policies.

Attack Complexity (AC) measures the difficulty in executing an exploit. A high AC means that specific conditions must be met, making an attack more challenging, while a low AC means the vulnerability can be exploited with minimal effort.

Privileges Required (PR) determine the level of system access necessary for an attack. Vulnerabilities requiring no privileges are more accessible to attackers, whereas high privilege requirements limit exploitation to authorized users with elevated access.

CVSS Score Breakdown Chart

Above is the CVSS Sub-score Breakdown for CVE-2025-54429, illustrating how Base, Impact, and Exploitability factors combine to form the overall severity rating. A higher sub-score typically indicates a more severe or easier-to-exploit vulnerability.

CIA Impact Analysis
