CVE-2025-62370: 
Rust vulnerability analysis and mitigation

CVE-2025-62370 affects the Alloy Core libraries, which are fundamental to the Rust Ethereum ecosystem. The vulnerability was discovered and disclosed on October 15, 2025, impacting versions prior to 0.8.26 and 1.4.1 of the alloy-dyn-abi package. The issue involves an uncaught panic in the alloy_dyn_abi::TypedData component that could be triggered through malformed input (GitHub Advisory, RustSec).

The vulnerability is tracked as CWE-248 (Uncaught Exception) and CWE-20 (Improper Input Validation). It has received a CVSS v3.1 base score of 7.5 (HIGH) with the vector string CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H. The issue specifically occurs in the eip712_signing_hash() function when processing malformed input to alloy_dyn_abi::TypedData, where an uncaught panic is triggered when accessing the first element of an empty set (GitHub Advisory).

The vulnerability can lead to a denial-of-service (DoS) condition when exploited. Systems with high availability requirements, particularly network services, are most significantly impacted. While external auto-restarting mechanisms can provide partial mitigation, they may not be effective against repeated attacks (GitHub Advisory, RustSec).

The vulnerability has been patched in versions 0.8.26 and 1.4.1 of the alloy-dyn-abi package. The fix implements a check to ensure elements are not empty before accessing their first element, returning an error if empty. There are no known workarounds, and upgrading to a patched version is the recommended course of action (GitHub Advisory, RustSec).

The vulnerability was reported by Christian Reitter & Zeke Mostov from Turnkey, demonstrating active security research in the Rust Ethereum ecosystem (GitHub Advisory).
