CVE-2025-62370
Alloy Core has a DoS vulnerability on `alloy_dyn_abi::TypedData` hashing
Reported by github_m · Published October 15, 2025
alloy-dyn-abi is fixed in 1.4.1, 1.0.0 and 0.8.26 (crates.io)
Alloy Core libraries at the root of the Rust Ethereum ecosystem. Prior to 0.8.26 and 1.4.1, an uncaught panic triggered by malformed input to alloy_dyn_abi::TypedData could lead to a denial-of-service (DoS) via eip712_signing_hash(). Software with high availability requirements such as network services may be particularly impacted. If in use, external auto-restarting mechanisms can partially mitigate the availability issues unless repeated attacks are possible. The vulnerability was patched by adding a check to ensure the element is not empty before accessing its first element; an error is returned if it is empty. The fix is included in version v1.4.1 and backported to v0.8.26.
