⚠️ Risk & Real-World Impact

🔴

Worst Case

Complete draining of funds from vulnerable contracts and protocols built on Evmos through arbitrary token minting and manipulation.

🟠

Likely Case

Targeted exploitation of specific vulnerable smart contracts to mint tokens or manipulate DeFi protocols for financial gain.

🟢

If Mitigated

Limited impact if contracts have additional safeguards, but core vulnerability remains exploitable.

🌐 Internet-Facing: HIGH

🏢 Internal Only: HIGH

🎯 Exploit Status

Public PoC: ✅ No

Weaponized: LIKELY

Unauthenticated Exploit: ⚠️ Yes

Complexity: MEDIUM

Exploitation requires smart contract interaction knowledge but no authentication. Public details suggest sophisticated attackers could weaponize.

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: V17.0.0 and later

Vendor Advisory: https://github.com/evmos/evmos/security/advisories/GHSA-3fp5-2xwh-fxm6

Restart Required: Yes

Instructions:

1. Stop Evmos node. 2. Backup configuration and data. 3. Update to V17.0.0 or later. 4. Restart node with updated binary.

🔧 Temporary Workarounds

No effective workarounds

all

This is a core blockchain protocol vulnerability requiring patching.

🧯 If You Can't Patch

Monitor for suspicious token minting transactions and contract interactions
Consider temporarily pausing vulnerable smart contracts or limiting interactions

🔍 How to Verify

Check if Vulnerable:

Check Evmos version: evmosd version

Check Version:

evmosd version

Verify Fix Applied:

Confirm version is V17.0.0 or later: evmosd version

📡 Detection & Monitoring

Log Indicators:

Unexpected token minting events
Unusual smart contract state changes
Failed state synchronization errors

Network Indicators:

Abnormal transaction patterns involving state manipulation
Multiple contract calls in single transaction with state changes

SIEM Query:

transaction_logs WHERE contract_interaction_count > threshold AND token_minting_events > 0
