From 4e4880545c326a233f219a0f4be9ab63851ec847 Mon Sep 17 00:00:00 2001 From: ety001 Date: Fri, 10 Jul 2026 10:46:05 +0800 Subject: [PATCH 1/7] =?UTF-8?q?fix(security):=20P0=20broadcast=20integrity?= =?UTF-8?q?=20=E2=80=94=20op-type=20enforcement,=20DB=20gate,=20honest=20v?= =?UTF-8?q?erifySignature?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Three critical audit findings on the write/broadcast path: 1. recover-account: return 503 when MySQL is unavailable (was: skip the recovery-record cross-check and broadcast anyway). This is the only application-layer gate on the account-takeover path; fail-closed to match recovery/request and recovery/confirm. 2. Enforce the operation type on every broadcast route. Previously only account-update validated operations[0][0]; the other 15 routes relayed any signed operation verbatim, so a transfer could be posted to /vote to use its higher rate-limit budget. New assertSignedTxOpType() helper applied to all routes. 3. Rename the misleading verifySignature() to validateTransactionShape() with a security note: it checks transaction shape only, not signatures — the chain rejects bad signatures on broadcast. Real crypto verification is tracked separately (needs serializeTransaction exported upstream). Adds tests for the DB-unavailable→503 gate and the op-type helper. --- src/app/api/broadcast/account-create/route.ts | 13 +++- src/app/api/broadcast/account-update/route.ts | 10 +-- src/app/api/broadcast/convert/route.ts | 13 +++- src/app/api/broadcast/delegate/route.ts | 11 ++- .../api/broadcast/limit-order-cancel/route.ts | 13 +++- .../api/broadcast/limit-order-create/route.ts | 13 +++- src/app/api/broadcast/power-down/route.ts | 13 +++- .../api/broadcast/proposal-create/route.ts | 9 ++- .../api/broadcast/proposal-remove/route.ts | 9 ++- src/app/api/broadcast/proposal-vote/route.ts | 13 +++- .../api/broadcast/recover-account/route.ts | 71 ++++++++++--------- .../set-withdraw-vesting-route/route.ts | 13 +++- src/app/api/broadcast/transfer/route.ts | 13 +++- src/app/api/broadcast/vote/route.ts | 13 +++- src/app/api/broadcast/witness-proxy/route.ts | 13 +++- src/app/api/broadcast/witness-vote/route.ts | 13 +++- src/lib/steem/server.ts | 69 ++++++++++++++++-- src/lib/steem/validate-signed-tx-op.ts | 22 ++++++ .../broadcast-recover-account-route.test.ts | 16 +++++ tests/unit/validate-signed-tx-op.test.ts | 52 ++++++++++++++ 20 files changed, 329 insertions(+), 83 deletions(-) create mode 100644 src/lib/steem/validate-signed-tx-op.ts create mode 100644 tests/unit/validate-signed-tx-op.test.ts diff --git a/src/app/api/broadcast/account-create/route.ts b/src/app/api/broadcast/account-create/route.ts index 3178fd1f..4b036db2 100644 --- a/src/app/api/broadcast/account-create/route.ts +++ b/src/app/api/broadcast/account-create/route.ts @@ -2,9 +2,10 @@ // Broadcast a signed account_create transaction (community creation step 1) import { NextRequest, NextResponse } from 'next/server';

Wire it into all 17 broadcast routes via validateRelayTransaction(), which now combines op-type enforcement AND crypto verification in one call: - 15 standard routes: validateRelayTransaction(signedTx, opType, username) - account-update: verifyTransactionForUsername after its existing shape check - recover-account: verifies against the recent_owner_authority pubkey in the op body (recover_account is signed by the OLD owner key, which may not be in the account's current authority set) This closes the audit's Critical #1 gap: the server now proves the signer holds a key on the claimed account BEFORE relaying the broadcast, rather than relying on shape-check + chain rejection alone. --- package.json | 2 +- pnpm-lock.yaml | 10 +- pnpm-workspace.yaml | 3 + src/app/api/broadcast/account-create/route.ts | 15 +-- src/app/api/broadcast/account-update/route.ts | 12 +- src/app/api/broadcast/convert/route.ts | 15 +-- src/app/api/broadcast/custom-json/route.ts | 15 +-- src/app/api/broadcast/delegate/route.ts | 19 +--- .../api/broadcast/limit-order-cancel/route.ts | 15 +-- .../api/broadcast/limit-order-create/route.ts | 15 +-- src/app/api/broadcast/power-down/route.ts | 19 +--- .../api/broadcast/proposal-create/route.ts | 15 +-- .../api/broadcast/proposal-remove/route.ts | 15 +-- src/app/api/broadcast/proposal-vote/route.ts | 15 +-- .../api/broadcast/recover-account/route.ts | 18 ++- .../set-withdraw-vesting-route/route.ts | 15 +-- src/app/api/broadcast/transfer/route.ts | 19 +--- src/app/api/broadcast/vote/route.ts | 19 +--- src/app/api/broadcast/witness-proxy/route.ts | 15 +-- src/app/api/broadcast/witness-vote/route.ts | 19 +--- src/lib/steem/server.ts | 106 ++++++++++++++---- src/lib/steem/validate-signed-tx-op.ts | 36 ++++++ tests/mocks/steem-js.ts | 5 + .../broadcast-recover-account-route.test.ts | 20 +++- tests/unit/proposals-broadcast-routes.test.ts | 11 +- 25 files changed, 262 insertions(+), 206 deletions(-) diff --git a/package.json b/package.json index d53482b6..6a3ba79b 100644 --- a/package.json +++ b/package.json @@ -19,7 +19,7 @@ }, "dependencies": { "@reduxjs/toolkit": "^2.11.2", - "@steemit/steem-js": "^1.0.19", + "@steemit/steem-js": "^1.0.20", "class-variance-authority": "^0.7.1", "clsx": "^2.1.1", "drizzle-orm": "^0.45.2", diff --git a/pnpm-lock.yaml b/pnpm-lock.yaml index aaba4a2f..d033435c 100644 --- a/pnpm-lock.yaml +++ b/pnpm-lock.yaml @@ -12,8 +12,8 @@ importers: specifier: ^2.11.2 version: 2.11.2(react-redux@9.2.0(@types/react@19.2.14)(react@19.2.5)(redux@5.0.1))(react@19.2.5) '@steemit/steem-js': - specifier: ^1.0.19 - version: 1.0.19 + specifier: ^1.0.20 + version: 1.0.20 class-variance-authority: specifier: ^0.7.1 version: 0.7.1 @@ -2321,8 +2321,8 @@ packages: '@standard-schema/utils@0.3.0': resolution: {integrity: sha512-e7Mew686owMaPJVNNLs55PUvgz371nKgwsc4vxE49zsODpJEnxgxRo2y/OKrqueavXgZNMDVj3DdHFlaSAeU8g==} - '@steemit/steem-js@1.0.19': - resolution: {integrity: sha512-XQ27tINwn41P5Iu5bICX4Mn4ZT0/e+tK4KVYEQPOu/vvrndUu/kc9C/2Px0AUP0UuotOtX7slfMLJdbgKK5zLw==} + '@steemit/steem-js@1.0.20': + resolution: {integrity: sha512-JHScKe3A7WyuLKl1X6feTbh42oqylBeBXZP1VxG5pABk0jMkJv59rEo3pk9MruhU3IAUKYGj0DesG+D01I93jA==} engines: {node: '>=20.19.0'} '@swc/core-darwin-arm64@1.15.30': @@ -7935,7 +7935,7 @@ snapshots: '@standard-schema/utils@0.3.0': {} - '@steemit/steem-js@1.0.19': + '@steemit/steem-js@1.0.20': dependencies: '@noble/ciphers': 2.2.0 '@noble/hashes': 2.2.0 diff --git a/pnpm-workspace.yaml b/pnpm-workspace.yaml index 0abe018c..4abc7cf7 100644 --- a/pnpm-workspace.yaml +++ b/pnpm-workspace.yaml @@ -8,3 +8,6 @@ allowBuilds: msw: true sharp: false unrs-resolver: false + +minimumReleaseAgeExclude: + - '@steemit/steem-js@1.0.20' diff --git a/src/app/api/broadcast/account-create/route.ts b/src/app/api/broadcast/account-create/route.ts index 4b036db2..bffe02b4 100644 --- a/src/app/api/broadcast/account-create/route.ts +++ b/src/app/api/broadcast/account-create/route.ts @@ -5,7 +5,7 @@ import { SteemService } from '@/lib/steem/server';
