CVE-2025-62370: Alloy Core has a DoS vulnerability on `alloy_dyn_abi::TypedData` hashing
Impact
An uncaught panic triggered by malformed input to alloydynabi::TypedData could lead to a denial-of-service (DoS) via eip712signinghash().
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.
Patches
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.
Workarounds
There is no known workaround that mitigates the vulnerability. Upgrading to a patched version is the recommended course of action.
