CVE-2025-62370
📋 TL;DR
This vulnerability in Alloy Core libraries allows attackers to cause denial-of-service (DoS) by sending malformed input to the eip712_signing_hash() function, triggering an uncaught panic that crashes the application. It affects Rust-based Ethereum applications using vulnerable versions of alloy-dyn-abi. High-availability services like network nodes are particularly vulnerable to availability disruption.
💻 Affected Systems
- Rust applications using alloy-dyn-abi library
⚠️ Manual Verification Required
This CVE does not have specific version information in our database, so automatic vulnerability detection cannot determine if your system is affected.
Why? The CVE database entry doesn't specify which versions are vulnerable (no version ranges provided by the vendor/NVD).

⚠️ Risk & Real-World Impact
Worst Case
Complete service outage for Ethereum applications, potentially disrupting blockchain operations, transaction processing, or smart contract execution until manual restart.
Likely Case
Service crashes requiring restart, causing temporary downtime and potential transaction failures or synchronization issues in Ethereum nodes.
If Mitigated
Minimal impact with auto-restart mechanisms, though repeated attacks could still cause availability degradation.
🎯 Exploit Status
Exploitation requires sending malformed input to the vulnerable function, which is straightforward for attackers familiar with the library.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 0.8.26 or 1.4.1
Vendor Advisory: https://github.com/alloy-rs/core/security/advisories/GHSA-pgp9-98jm-wwq2
Restart Required: Yes
Instructions:
1. Update Cargo.toml to specify alloy-dyn-abi >= 0.8.26 or >= 1.4.1. 2. Run 'cargo update alloy-dyn-abi'. 3. Rebuild and redeploy your application. 4. Restart affected services.
🔧 Temporary Workarounds
Input validation wrapper
allAdd custom validation to check for empty elements before calling eip712_signing_hash()
// Rust code: Validate input length before calling vulnerable function
🧯 If You Can't Patch
- Implement rate limiting on input endpoints to prevent repeated attacks
- Deploy auto-restart mechanisms with health checks to minimize downtime
🔍 How to Verify
Check if Vulnerable:
Check Cargo.lock or run 'cargo tree | grep alloy-dyn-abi' to see if version is below 0.8.26 or 1.4.1Check Version:
cargo tree | grep alloy-dyn-abiVerify Fix Applied:
Confirm version is 0.8.26+ or 1.4.1+ via 'cargo tree | grep alloy-dyn-abi' and test with malformed input📡 Detection & Monitoring
Log Indicators:
