finance-daily-report

• Outcome: Review
• Latest audit: Sep 12, 2026 · 1:25 AM UTC
• Version: 1.0.0

Overview

The skill mostly matches a finance daily report tool, but it needs Review because setup stores API keys insecurely and the scheduled workflow uses unsafe shared temporary files.

Review before installing. Use a dedicated unprivileged account, avoid entering API keys into the setup script as written, prefer a proper secret store or tightly permissioned environment file, inspect the cron job before enabling automatic delivery, and assume fetched public content will be sent to DashScope or Volcengine for processing.

Vulnerability Patterns

• Skill Instruction Hijacking: Alters the agent's session goals or safety constraints when the skill loads
• Insecure Skill Coding Practices: Finds exploitable flaws such as hardcoded secrets or command injection
• Agent Memory Poisoning: Writes attacker-controlled rules into memory that affect later sessions
• Remote Payload Retrieval and Execution: Fetches external code whose behavior can change after review
• Embedded Malicious Code: Ships malicious scripts inside the skill and executes them locally

Error

• Location: scripts/setup.sh:55
• Finding: API keys are entered visibly and persisted as plaintext shell configuration<![CDATA[ ## Vulnerability Details **File Location**: `scripts/setup.sh`, lines 55-64 and 84-89 **Vulnerability Type**: Plaintext credential storage and visible secret input **Risk Level**: High ### Vulnerable Code ```bash read -rp " 请输入 DashScope API Key（留空则使用 sub-agent / 主 agent 默认配置）: " INPUT_DASHSCOPE if [ -n "$INPUT_DASHSCOPE" ]; then export DASHSCOPE_API_KEY="$INPUT_DASHSCOPE" if [ -n "$SHELL_RC" ]; then if ! grep -q "DASHSCOPE_API_KEY" "$SHELL_RC"; then echo "" >> "$SHELL_RC" echo "# Finance Daily Report — DashScope API Key" >> "$SHELL_RC" echo "export DASHSCOPE_API_KEY=\"$INPUT_DASHSCOPE\"" >> "$SHELL_RC" echo -e "${GREEN}✓ 已写入 $SHELL_RC${NC}" fi fi fi ``` ```bash read -rp " 可选：输入豆包 API Key 作为备用模型（留空跳过）: " INPUT_DOUBAO if [ -n "$INPUT_DOUBAO" ]; then export DOUBAO_API_KEY="$INPUT_DOUBAO" if [ -n "$SHELL_RC" ] && ! grep -q "DOUBAO_API_KEY" "$SHELL_RC"; then echo "export DOUBAO_API_KEY=\"$INPUT_DOUBAO\"" >> "$SHELL_RC" echo -e "${GREEN}✓ DOUBAO_API_KEY 已写入 $SHELL_RC${NC}" fi fi ``` ### Technical Analysis The setup script uses `read -rp`, which does not suppress terminal echo. API keys are therefore displayed while the user types them and may be exposed to screen recording, terminal sharing, shoulder surfing, or terminal logging. The keys are subsequently written verbatim into `.bashrc` or `.zshrc`. These files are ordinary plaintext files and may be exposed through backups, diagnostic bundles, accidental repository commits, overly permissive home-directory permissions, or unrelated processes running under the same account. The script does not verify or harden the shell configuration file's permissions. It also writes user-controlled data into shell syntax without validating the expected API-key character set. A value containing shell substitution syntax such as `$(...)` would be stored literally and evaluated the next time the shell configurat ...[truncated 2010 chars]
• Remediation: <![CDATA[ ## Remediation Suggestions 1. Use hidden terminal input: ```bash read -rsp "Enter DashScope API key: " INPUT_DASHSCOPE printf '\n' ``` 2. Do not write credentials to `.bashrc` or `.zshrc`. Use the operating system's credential manager, OpenClaw's secret store, or a dedicated file readable only by the owner. 3. If a dedicated secret file is unavoidable: - Create it with `umask 077`. - Set mode `0600`. - Store it outside repositories and workspace directories. - Document deletion and rotation procedures. 4. Validate keys against the provider's expected character set and maximum length before storage. 5. Never generate executable shell source from untrusted credential input. If shell environment integration is required, safely quote the value using a robust shell-escaping mechanism rather than string interpolation. 6. Add a warning explaining which providers receive data and how credentials will be stored. 7. Rotate any API keys previously stored by the existing setup script and remove them from shell history, startup files, backups, and diagnostic archives where practical. ]]>

Warning

• Location: scripts/collect_and_structure.py:263
• Finding: Untrusted website content is embedded directly into LLM instructions without prompt-injection isolation<![CDATA[ ## Vulnerability Details **File Location**: `scripts/collect_and_structure.py`, lines 263-279 **Vulnerability Type**: Indirect prompt injection through externally controlled market and news content **Risk Level**: Medium ### Vulnerable Code ```python def extract_market_theme(raw_jin10, raw_cls, date): """Extract market theme from jin10 + cls data.""" prompt = f"""从以下金十数据快讯和财联社页面提取 {date} 的市场核心主线叙事。 金十数据每条新闻末尾都有"| URL: ..."，这是该条新闻的具体链接，请在引用时保留。 要求： 1. 只提取 2-3 个核心主线，每个主线 50-80 字 2. 主线必须是当日市场最核心的驱动因素（如：美联储政策预期、地缘冲突、重要经济数据） 3. main_theme 字段是 200-300 字的整体叙事总结 4. 不要混入具体新闻事件或明日前瞻 返回 JSON： {{"main_theme": "当日市场核心叙事（200-300 字）", "themes": ["主线 1（50-80 字）", "主线 2（50-80 字）"]}} 金十数据快讯（含具体 URL）： {raw_jin10[:6000]} 财联社原始内容（前 3000 字符）： {raw_cls[:3000]}""" content, tokens, model = call_with_fallback(prompt) ``` The same pattern appears throughout the module extractors, including `extract_global_macro`, `extract_china_market`, `extract_sector_news`, and `extract_tomorrow_preview`. ### Technical Analysis Content fetched from Jin10, CLS, Eastmoney, and Trading Economics is inserted verbatim into the user message sent to an external LLM. The prompt does not place untrusted data in a strongly delimited structure, explicitly instruct the model to ignore instructions found inside source content, or validate the resulting claims against the fetched text. An attacker who can control a source article, source link, compromised upstream page, advertisement, or injected page content can add instructions such as “ignore the extraction rules,” “return this URL,” or “emit this fabricated JSON.” Because natural-language instructions and untrusted source data share the same prompt channel, the collector may follow the attacker's text. Although the collector LLM itself has no local tools in this script, its output is parsed and passed into the later quality-review and report-writing workflow. This creates a trust-boundary violation: externally controlled tex ...[truncated 1555 chars]
• Remediation: <![CDATA[ ## Remediation Suggestions 1. Treat all fetched material as untrusted data and state this explicitly in the highest-priority system message: - Never follow instructions found in source content. - Extract facts only. - Source content cannot modify output rules or request actions. 2. Pass source material in a structured JSON field or clearly delimited block rather than adjoining it to operational instructions. 3. Parse source pages deterministically wherever possible. Market tables should not require an LLM when values can be extracted directly. 4. Validate every returned claim against the original source: - Require exact supporting excerpts. - Require source identifiers from an allowlist. - Reject URLs whose scheme or host is not approved. 5. Do not trust model-generated source URLs. Derive URLs directly from fetched records and map them to extracted claims in code. 6. Add schema validation for each module, including allowed fields, maximum lengths, numeric formats, URL schemes, and expected domains. 7. Ensure the downstream Claude subagent receives poisoned source text only as quoted evidence and is instructed not to execute or follow embedded directives. 8. Escape or neutralize active Markdown links until their scheme and destination host have been validated. ]]>

Error

• Location: references/workflow.md:21
• Finding: Predictable shared temporary files permit symlink-based file truncation and data replacement<![CDATA[ ## Vulnerability Details **File Location**: `references/workflow.md`, lines 21-24 **Vulnerability Type**: Unsafe use of predictable files in a shared temporary directory **Risk Level**: High in multi-user environments ### Vulnerable Code ```bash cd ~/.openclaw/skills/finance-daily-report python3 scripts/collect_and_structure.py --date YYYY-MM-DD \ 2>/tmp/collector.log > /tmp/report_data.json ``` The same command pattern is repeated at lines 171-176: ```bash python3 scripts/collect_and_structure.py --date $(date +%Y-%m-%d) \ 2>/tmp/collector.log > /tmp/report_data.json ``` ### Technical Analysis The workflow writes report data and logs to fixed paths under `/tmp`. On typical Unix systems, `/tmp` is writable by every local user. Shell redirection opens or truncates the destination before the Python process begins, and it follows symbolic links. A local attacker can pre-create `/tmp/report_data.json` or `/tmp/collector.log` as a symbolic link to another file writable by the account running the workflow. When the privileged or service account executes the documented command, the shell truncates and overwrites the symlink target. The fixed report filename also allows local data replacement. An attacker with access to the shared temporary namespace may race the workflow or replace the report after collection but before the Phase 2 subagent reads it. This can inject attacker-controlled content into the report-generation pipeline. The project documentation indicates that reports may run from `/root/.openclaw` and be saved under `/root/.openclaw/workspace`. If the workflow is executed as root, the symlink attack could affect root-writable files. Actual impact depends on runtime user, filesystem protections, and local access. ### Attack Path Symlink file-clobbering path: 1. A local attacker creates a symbolic link: ```bash ln -s /path/to/target /tmp/report_data.json ``` 2. The finance-report workflow runs under an account able to write t ...[truncated 1269 chars]
• Remediation: <![CDATA[ ## Remediation Suggestions 1. Create a private temporary directory with restrictive permissions: ```bash workdir="$(mktemp -d)" chmod 700 "$workdir" trap 'rm -rf -- "$workdir"' EXIT ``` 2. Write report and log files inside that directory rather than directly under `/tmp`. 3. Prefer creating files through Python with exclusive creation flags and mode `0600`. 4. Avoid shell redirection to predictable paths when the workflow may run with elevated privileges. 5. Pass the generated filename directly between workflow phases rather than relying on a global fixed path. 6. Verify file ownership, type, permissions, and link count before reading: - Reject symbolic links. - Require a regular file. - Require ownership by the workflow account. - Reject files writable by group or others. 7. Where supported, use descriptor-based operations with `O_NOFOLLOW`, `O_CREAT`, and `O_EXCL`. 8. Run the collector and report workflow as a dedicated unprivileged service account rather than root. ]]>

• Location: scripts/call_collector.py:35
• Finding: Arbitrary collector prompts are transmitted to external LLM providers without data classification or disclosure controls<![CDATA[ ## Vulnerability Details **File Location**: `scripts/call_collector.py`, lines 35-66 **Vulnerability Type**: Unrestricted external transmission of caller-supplied prompt data **Risk Level**: Medium ### Vulnerable Code ```python def call_llm(config, prompt, timeout=120): """Call an LLM and return the response content.""" headers = { "Content-Type": "application/json", "Authorization": f"Bearer {config['key']}", } system_prompt = """你是专业的金融数据采集助手。任务：从原始数据中提取结构化信息。 输出要求： 1. 只输出纯 JSON，不要用 ```json 或 ``` 包裹 2. 不要有任何额外文字、解释、注释 3.

There is no data classification, secret detection, redaction, size restriction, destination confirmation, or warning at the point of transmission. For the default collection pipeline, the transmitted data is predominantly public market and news content, and the use of external LLM collectors is declared in `SKILL.md`. That network behavior is necessary for the chosen architecture. The risk arises because the generic helper permits any caller-supplied prompt, including private conversation text, credentials, internal URLs, proprietary documents, or personal data, to cross the local trust ...[truncated 1621 chars]
• Remediation: <![CDATA[ ## Remediation Suggestions 1. Clearly warn callers that prompt content will be sent to DashScope or Volcengine before transmission. 2. Restrict the helper to the minimum collector schema needed by the skill instead of accepting unrestricted arbitrary prompts. 3. Add automated redaction for common secret formats, authorization headers, private keys, access tokens, and sensitive personal identifiers. 4. Reject prompts containing known secret markers or private-key blocks unless an explicit, audited override is provided. 5. Add a configurable provider allowlist and make fallback transmission to a second provider opt-in, since fallback changes the data recipient. 6. Document provider retention, residency, and privacy implications. 7. Avoid including conversation history, environment dumps, local configuration files, or workspace documents unless strictly necessary and explicitly authorized. 8. Log only metadata such as provider, timestamp, and token count; never log full prompt bodies or credentials. 9. Consider local deterministic extraction for structured public market data to reduce the amount of information sent externally. ]]>

Findings (37)

Tp4

High

• Category: MCP Tool Poisoning
• Confidence: 90% confidence
• Finding: The core reporting purpose mostly matches: the code does generate a 9-module global finance daily report using external LLMs and supports selective module collection. It also stays within the declared non-advice/reporting domain. However, the description claims additional operational capabilities—module management and setup/install for scheduled daily delivery—that are not present in this code chunk. The code is a standalone CLI collector only; it accepts --date and --module, fetches remote data sources, calls LLM APIs, and emits structured JSON to stdout. It does not implement chat delivery, auto-chunking, persistent configuration, enabling/disabling modules, adding/removing modules, or scheduling/setup flows. Therefore the description overstates the implemented capabilities in a material way.

Tp4

High

• Category: MCP Tool Poisoning
• Confidence: 97% confidence
• Finding: This code is narrowly focused on editing a finance-report configuration file. That partially aligns with the declared module-management aspect (add/remove/enable/disable/list). However, the declared purpose describes a full finance daily report skill with default modules, external collectors, chat output, and setup/install scheduling behavior. None of those core capabilities are implemented in the supplied code chunk. The primary observed behavior is config mutation via CLI, not report generation. Additionally, the code exposes a 'reorder' command in argparse and in the usage text, but there is no corresponding execution branch, so that advertised capability is absent. Because the declared description materially overstates what this code chunk does, this is a mismatch.

Lp3

Medium

• Category: MCP Least Privilege
• Confidence: 84% confidence
• Finding: The skill invokes privileged capabilities including cron management, spawning a subagent, reading workflow files, writing reports to disk, and using external collectors, but it declares no explicit tool/permission scope. That increases the blast radius if the skill is triggered unexpectedly or modified later, because the runtime may grant broader access than is necessary for finance reporting.

Natural-Language Policy Violations

Medium

• Confidence: 95% confidence
• Finding: The setup flow explicitly instructs the agent to use a fixed Chinese greeting and message to the user. This is a natural-language locale policy concern because the skill does not offer the user a language choice or document that the skill is intentionally limited to Chinese-only operation.

Context-Inappropriate Capability

Medium

• Confidence: 95% confidence
• Finding: The default configuration ships with a prebuilt module focused on AI agent asset management, investment products, and portfolio-management-adjacent topics even though the skill metadata explicitly says it is not for real-time trading, individual stock analysis, or investment advice. Although disabled by default, including this module expands the skill into a higher-risk financial domain and makes scope creep easier, especially if users enable it without understanding the boundary between news reporting and investment-oriented analysis.

Natural-Language Policy Violations

Medium

• Confidence: 91% confidence
• Finding: The file presents the skill entirely as a Chinese-language prompt template for subagents, including role and output guidance, with no indication that users may choose another language. Under the policy rule, forcing a specific language without opt-in is a natural-language policy violation unless the locale restriction is explicitly justified.

Missing User Warnings

Medium

• Confidence: 92% confidence
• Finding: The file instructs the agent to perform persistent module-management actions that modify future report behavior, but it provides no requirement to warn the user, confirm destructive changes, or distinguish informational queries from state-changing commands. In a skill that supports natural-language administration, this creates a real risk of unintended or socially engineered configuration changes that persist across future runs.

Natural-Language Policy Violations

Medium

• Confidence: 88% confidence
• Finding: The schema explicitly specifies that the module display name should be Chinese (`显示名称（中文）`), which imposes a language requirement in the skill's natural-language documentation. This appears to force a specific language without user opt-in or a documented region-specific justification, matching the language/locale policy violation category.

Natural-Language Policy Violations

Medium

• Confidence: 93% confidence
• Finding: The entire document is written in Chinese and includes Chinese-only source descriptions and instructions, with no indication that language choice is optional or that the skill is intentionally limited to a Chinese-speaking context. Under the policy rule, forcing a specific language without user opt-in is a natural-language policy violation.

Natural-Language Policy Violations

Medium

• Confidence: 95% confidence
• Finding: The title and template are written as a fixed Chinese-language daily report format, indicating the skill outputs in Chinese by default. The instructions also prescribe a specific locale/timezone format rather than offering a language or locale choice.

Natural-Language Policy Violations

Medium

• Confidence: 91% confidence
• Finding: The template requires timestamps in the Asia/Shanghai timezone, which is a locale constraint. Under the policy, forcing a locale without user choice or clear region-specific justification is a natural-language policy concern.

Natural-Language Policy Violations

Medium

• Confidence: 96% confidence
• Finding: The instruction '所有时间标注 Asia/Shanghai' imposes a fixed locale/timezone on all outputs. The file does not offer an alternative locale or explicit opt-in, which conflicts with the language/locale policy criteria.

Natural-Language Policy Violations

Medium

• Confidence: 95% confidence
• Finding: The entire skill specification is written as a mandatory Chinese-language workflow and examples, with no indication that users may opt into another language or locale. This creates a natural-language policy concern because it effectively imposes a specific language choice rather than offering flexibility or documenting a justified locale restriction.

Missing User Warnings

Medium

• Confidence: 95% confidence
• Finding: This script sends the caller-supplied prompt directly to third-party LLM APIs (DashScope and Volcengine) with no consent gate, redaction, or disclosure mechanism. In a finance reporting skill, prompts may contain proprietary research, internal business context, user identifiers, or scheduled-report configuration details, so silent transmission to external providers creates a real privacy and data-governance risk even if the code is functionally intended.

Missing User Warnings

Medium

• Confidence: 94% confidence
• Finding: The script sends large amounts of third-party collected content from Jin10, CLS, Eastmoney, and Trading Economics directly to external LLM providers for processing, but there is no user-facing disclosure, consent flow, or data-handling guardrail. In this skill context, that matters because news content, source URLs, and potentially provider-specific licensed content are exfiltrated to external model vendors, creating privacy, compliance, and contractual-use risk even if the data is not obviously secret.

Natural-Language Policy Violations

Medium

• Confidence: 95% confidence
• Finding: The embedded system prompt instructs the model in Chinese and requires a fixed output behavior without any user opt-in or locale selection mechanism. This enforces a specific language/locale policy in a way that may violate organizational requirements for user choice unless the regional constraint is explicitly documented and justified.

Natural-Language Policy Violations

Medium

• Confidence: 95% confidence
• Finding: The request headers hard-code `Accept-Language: zh-CN,zh;q=0.9,en;q=0.8`, which explicitly prefers Chinese responses for all fetches. This is a natural-language locale policy concern because the skill imposes a language preference without offering user choice or documenting a justified region-specific requirement.

Description-Behavior Mismatch

Medium

• Confidence: 98% confidence
• Finding: The file-level usage documentation says the script supports `reorder --name ... --priority ...`, which aligns with the manifest's module management scope. However, although CLI arguments for `reorder` are defined later, there is no `cmd_reorder` function and the dispatch logic never handles `args.command == "reorder"`, so the advertised behavior does not occur.

• Finding: Data from a source is assigned to a variable that is later passed to a sink, creating a variable-mediated taint flow.

Missing User Warnings

Medium

• Confidence: 91% confidence
• Finding: The remove command deletes a module definition from the configuration and immediately writes the modified file back to disk. Although the code prints a success message afterward, there is no confirmation prompt or pre-action warning before this potentially irreversible file modification.

• Finding: Data from a source is assigned to a variable that is later passed to a sink, creating a variable-mediated taint flow.

Natural-Language Policy Violations

Medium

• Confidence: 92% confidence
• Finding: This Python file contains multiple natural-language strings in Chinese for module names and user-facing recommendations, such as the module labels in the source list and printed guidance like '数据暂缺'. The file does not offer any language selection or document that the skill is intentionally region-specific, which can violate a language/locale policy requiring user choice or justified locale constraints.

Natural-Language Policy Violations

Medium

• Confidence: 96% confidence
• Finding: The report content is generated with fixed Chinese headings, labels, and narrative markers throughout the script, such as section titles and footer text. Because the file does not provide any user opt-in, language selection, or justification that the skill is intended only for a Chinese-language environment, it appears to enforce a specific locale in violation of the language/locale policy.
