Vulnerability in github.com/ixofoundation/ixo-blockchain/v8 (CVE-2026-61604)

Summary

Vulnerability in github.com/ixofoundation/ixo-blockchain/v8 (CVE-2026-61604). Risk of unauthorized operations or information disclosure. Mitigation: upgrade to 8.0.0 or later.

Original description

The description as published by the source.

Impact

Type: Improper authorization leading to unauthorized movement of user funds.

The x/bonds module moved funds from an address that was resolved from a DID verification method, without verifying that the resolved address belonged to the transaction signer. Affected handlers included MsgMakeOutcomePayment, MsgBuy, MsgSell, MsgSwap, and MsgWithdrawShare, as well as the batch order processor.

Because any account may list an arbitrary blockchainAccountID as a verification method on a DID it controls (without the consent of that address's owner), an attacker could register victims' addresses as verification methods on their own DID and then move the victims' balances into a bond the attacker controlled — later withdrawing and bridging the proceeds off-chain.

This was exploited on ixo mainnet (ixo-5) on 2026-06-20. The attack required no victim keys, signatures, or system compromise — any account holding a balance in a token a bond could use was at risk.

Patches

Fixed in v8.0.0, delivered via the on-chain v8 software-upgrade. The x/bonds module is disabled: every bonds message is rejected on all routes (top-level, authz, CosmWasm, and ICA), and the bonds batch EndBlocker is a no-op so no further reserve movements can occur.

All node operators and validators must upgrade to v8.0.0. The flaw is in chain state-machine logic and can only be remediated by running the patched binary.

Workarounds

There is no application-level workaround. The vulnerability is…

Response actions

Concrete steps and command examples for SOC/SRE teams to execute in order

  1. 1
    Identify exposure identify 
    grep -r 'github.com/ixofoundation/ixo-blockchain/v8' . | grep -v node_modules

    リポジトリと本番環境の依存ファイル (package-lock.json / requirements.txt / go.sum / Gemfile.lock 等) で github.com/ixofoundation/ixo-blockchain/v8 を grep し、稼働しているサービス・バージョンを把握する。

  2. 2
    Apply patch patch 
    Upgrade github.com/ixofoundation/ixo-blockchain/v8 to 8.0.0

    ステージング環境で 8.0.0 に上げて回帰テスト → 本番反映。回帰テストはアプリの主要ハッピーパスを含めること。

  3. 3
    Post-deployment verification verify 
    Confirm patched version is live in production

    パッチ適用後、ステージングで PoC または同等の悪用パターンを再現して脆弱性が閉じたことを確認。本番ではアクセスログ・WAF でアラート再発が無いか継続監視。
