  "details": "### Summary\nThe GoCardless components in Actualbudget in are logging responses to STDOUT in a parsed format using `console.log`and `console.debug` (Which in this version of node is an alias for `console.log`). This is exposing sensitive information in log files including, but not limited to:\n\n- Gocardless bearer tokens.\n- Account IBAN and Bank Account numbers.\n- PII of the account holder.\n- Transaction details (Payee bank information, Recipient account numbers, Transaction IDs)...\n\n### Details\n\nWhenever GoCardless responds to a request, the payload is printed to the debug log: \nhttps://github.com/actualbudget/actual/blob/36c40d90d2fe09eb1f25a6e2f77f6dd40638b267/packages/sync-server/src/app-gocardless/banks/integration-bank.js#L25-L27\n\nThis in turn logs the following information to Docker (all values removed here. These fields are possibly dependent on what is returned by each institution so may differ):\n\n```json\n{\n  \"account\": {\n    \"resourceId\": \"\",\n    \"iban\": \"\",\n    \"bban\": \"\",\n    \"currency\": \"\",\n    \"name\": \"\u003cfull legal name in the bank\u003e\",\n    \"product\": \"\",\n    \"status\": \"\",\n    \"bic\": \"\",\n    \"usage\": \"\",\n    \"id\": \"\",\n    \"created\": \"\",\n    \"last_accessed\": \"\",\n    \"institution_id\": \"\",\n    \"owner_name\": \"\",\n    \"institution\": {\n      \"id\": \"\",\n      \"name\": \"\",\n      \"bic\": \"\",\n      \"transaction_total_days\": \"\",\n      \"countries\": [\n        \"\"\n      ],\n      \"logo\": \"\",\n      \"max_access_valid_for_days\": \"\",\n      \"supported_features\": [\n        \"\",\n        \"\",\n        \"\"\n      ],\n      \"identification_codes\": []\n    }\n  }\n}\n```\n\nhttps://github.com/actualbudget/actual/blob/36c40d90d2fe09eb1f25a6e2f77f6dd40638b267/packages/sync-server/src/app-gocardless/banks/integration-bank.js#L83-L85\n\nThis is the first of the 10 transactions:\n```json\n{\n  \"top10Transactions\": [{\n    \"transactionId\": \"\",\n    \"entryReference\": \"\",\n    \"bookingDate\": \"\",\n    \"valueDate\": \"\",\n    \"transactionAmount\": {\n      \"amount\": \"\",\n      \"currency\": \"\"\n    },\n    \"creditorName\": \"\",\n    \"creditorAccount\": {\n      \"bban\": \"\"\n    },\n    \"debtorName\": \"\",\n    \"debtorAccount\": {\n      \"bban\": \"\"\n    },\n    \"remittanceInformationUnstructured\": \"\",\n    \"remittanceInformationStructuredArray\": [\n      {\"reference\": \"\", \"referenceType\": \"\"}\n    ],\n    \"additionalInformation\": \"\",\n    \"proprietaryBankTransactionCode\": \"\",\n    \"debtorAgent\": \"\",\n    \"internalTransactionId\": \"\",\n    \"payeeName\": \"\",\n    \"date\": \"\"\n  }]\n}\n```\n\nAdditionally, in the error handling for GoCardless, there is a catch all for unclassified errors that prints the entire stack trace to the console.\n\nhttps://github.com/actualbudget/actual/blob/36c40d90d2fe09eb1f25a6e2f77f6dd40638b267/packages/sync-server/src/app-gocardless/app-gocardless.js#L263-L264\n\nOur bank was offline today for maintenance which threw a 503 error from Gocardless. The entire response payload was dumped to console, which includes the Bearer tokens for accessing GoCardless:\n\n```java\nSomething went wrong ServiceError: Institution service unavailable\n    at handleGoCardlessError (file:///app/src/app-gocardless/services/gocardless-service.js:59:13)\n    at Object.getTransactions (file:///app/src/app-gocardless/services/gocardless-service.js:530:7)\n    at process.processTicksAndRejections (node:internal/process/task_queues:95:5)\n    at async Object.getNormalizedTransactions (file:///app/src/app-gocardless/services/gocardless-service.js:267:26)\n    at async file:///app/src/app-gocardless/app-gocardless.js:186:13 {\n  details: h [AxiosError]: Request failed with status code 503\n      at te (file:///app/node_modules/nordigen-node/dist/index.esm.js:13:914)\n      at IncomingMessage.\u003canonymous\u003e (file:///app/node_modules/nordigen-node/dist/index.esm.js:17:16315)\n      at IncomingMessage.emit (node:events:529:35)\n      at endReadableNT (node:internal/streams/readable:1400:12)\n      at process.processTicksAndRejections (node:internal/process/task_queues:82:21) {\n    code: \u0027ERR_BAD_RESPONSE\u0027,\n    config: {\n      transitional: {\n        silentJSONParsing: true,\n        forcedJSONParsing: true,\n        clarifyTimeoutError: false\n      },\n      adapter: [ \u0027xhr\u0027, \u0027http\u0027 ],\n      transformRequest: [ [Function (anonymous)] ],\n      transformResponse: [ [Function (anonymous)] ],\n      timeout: 0,\n      xsrfCookieName: \u0027XSRF-TOKEN\u0027,\n      xsrfHeaderName: \u0027X-XSRF-TOKEN\u0027,\n      maxContentLength: -1,\n      maxBodyLength: -1,\n      env: {\n        FormData: [Function: _] {\n          LINE_BREAK: \u0027\\r\\n\u0027,\n          DEFAULT_CONTENT_TYPE: \u0027application/octet-stream\u0027\n        },\n        Blob: [class Blob]\n      },\n      validateStatus: [Function: validateStatus],\n      headers: T [AxiosHeaders] {\n        Accept: \u0027application/json\u0027,\n        \u0027Content-Type\u0027: \u0027application/json\u0027,\n        \u0027User-Agent\u0027: \u0027Nordigen-Node-v2\u0027,\n        \u0027Authorization\u0027: \u0027Bearer eyJ0eXAi...

In this instance I was using the Docker Compose script posted in the repository: https://github.com/actualbudget/actual/blob/master/packages/sync-server/docker-compose.yml\n- Link a gocardless account to Actualbudget and sync a bank account\n- Observe in the container using `docker logs actual-actual_server-1 -f`  that sensitive details are logged to the console and ingested by docker. \n\n### Impact\nInformation disclosure. The services are available both on-premises and in environments that are not under the control of the end user, such as third-party providers who offer this application as a managed solution.",
