What is CVE-2025-53359?

The Ethereum crate for Rust, prior to version v0.18.0, exhibited a specification deviation that failed to check for signature malleability in EIP-2930, EIP-1559, and EIP-7702 transactions. While signature malleability itself does not present a critical security threat on single-implementation blockchains, it is advisable to upgrade to version v0.18.0 to ensure compliance with specifications. A workaround involves conducting manual checks for transaction malleability outside of the crate.

Affected Version(s)

ethereum < 0.18.0
