CVE-2025-62370: Alloy Core has a DoS vulnerability on `alloy_dyn_abi::TypedData` hashing

• Severity: high (CVSS 7.5 v3.1)
• Exploited in the wild: not listed in CISA KEV
• EPSS: 0.4% probability of exploitation in the next 30 days
• Public exploit or detection template: none known

• Weakness: CWE-248

Description

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.

Affected products

• alloy-rs core: before 0.8.26; from 1.0.0, < 1.4.1
