What is CVE-2025-53359?
CVE-2025-53359 is a medium-severity vulnerability in rust-ethereum ethereum, published on 2 Jul 2025. An attacker can exploit it over the internet without logging in, with no action from the victim.
Official description
ethereum is a common ethereum structs for Rust. Prior to ethereum crate v0.18.0, signature malleability (according to EIP-2) was only checked for "legacy" transactions, but not for EIP-2930, EIP-1559 and EIP-7702 transactions. This is a specification deviation. The signature malleability itself is not a security issue and not as high of a risk if the ethereum crate is used on a single-implementation blockchain. This issue has been patched in version v0.18.0. A workaround for this issue involves manually checking transaction malleability outside of the crate, however upgrading is recommended.
Weakness: CWE-754
