Security checks for vulnerabilities and agentic risk

Overview

The skill largely matches its AI news workflow purpose, but it needs review because it can send content and an Ark API key to configurable network endpoints and crawl arbitrary configured URLs.

Install only if you trust the source spreadsheets and config.yaml. Keep ARK_API_KEY in the environment, leave ark.base_url pointed at the official Volcengine Ark endpoint, avoid submitting confidential articles, and run the crawler in a network-restricted environment so configured sources cannot reach localhost, cloud metadata, or private intranet services.

However, the client endpoint is independently controlled by the `ark.base_url` configuration value. There is no validation that the configured URL: - Uses HTTPS. - Belongs to the official Volcengine Ark domain. - Resolves to an approved public address. - Preserves the approved origin after redirects. The OpenAI client authenticates requests to the configured endpoint using the supplied API key. Consequently, an attacker who can provide or modify `config.yaml` can direct cred ...[truncated 1499 chars]

Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
91% confidence
Finding

The documentation explicitly states that the workflow generates '中文标题 + 摘要', which imposes a specific output language. Under the policy rules, forcing a language without offering a user choice or documenting an opt-in is a natural-language policy violation.

Content

Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
88% confidence
Finding

The skill description states that it optionally generates Chinese titles and summaries, but it does not indicate user choice beyond a vague optional capability or explain why Chinese output is the default or expected locale. This can lead to unexpected transformation of content into another language, which may introduce compliance, usability, or data-handling concerns in workflows that require preserving original language or user-selected locale.

Content

Missing User Warnings

Medium
Category
Not specified by scanner
Confidence
95% confidence
Finding

The skill documents use of the Ark API key and model selection but do not warn users that article content, titles, summaries, or other processed data may be transmitted to an external third-party service for generation. This can cause unintentional disclosure of proprietary, personal, or regulated information because users are not given clear notice or a chance to opt out before external network transfer.

Confidence
94% confidence
Finding

This code hard-codes a default locale-related setting with DEFAULT_TZ = "Asia/Shanghai", which effectively imposes a specific regional timezone when callers do not provide one. Under the policy, forcing a locale without user choice or clear justification is a natural-language policy concern, and the later compatibility helper reinforces this default behavior.

Confidence
91% confidence
Finding

The file fixes all time handling to Asia/Shanghai via a global constant, which is a locale-specific behavior. Under the policy, forcing a specific locale without user choice or clear region-specific justification is a natural-language policy concern, and the surrounding comments/docstrings do not document why this locale is required.

Confidence
93% confidence
Finding

The file fixes all time calculations to ZoneInfo("Asia/Shanghai"), which imposes a specific locale/timezone policy in code. There is no natural-language justification or opt-in mechanism indicating that the skill is intentionally region-specific, so this can violate language/locale policy expectations.

Content

Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
93% confidence
Finding

The class docstring, default filename prefix, sheet content labels, and column headers are all hard-coded in Chinese, which imposes a specific language/locale choice in the generated artifact. Under the language policy rule, this is a violation unless the skill offers a language choice or clearly documents a justified locale restriction.

Natural-Language Policy Violations

Medium
Category

Confidence
95% confidence
Finding

The class docstring and section titles indicate the exporter is hard-wired for Chinese briefing content, and later lines set only Chinese fonts such as 仿宋_GB2312 and 方正小标宋简体. This is a natural-language locale policy concern because the skill forces a specific language/locale presentation without offering opt-in or alternative locale handling.

Confidence
93% confidence
Finding

The docstrings and exception text are written only in Chinese, which imposes a specific language on users and maintainers without any opt-in or indication that the skill is intentionally limited to a Chinese-language context. Under the policy, forcing a specific language without user choice is a natural-language policy violation.

Confidence
90% confidence
Finding

The module hard-codes ZoneInfo("Asia/Shanghai") and later applies it to all parsed dates, which imposes a specific locale/timezone policy by default. The file does not indicate that this parser is intentionally region-specific or provide any opt-in or override mechanism.

Missing User Warnings

Medium
Category
Not specified by scanner
Confidence
93% confidence
Finding

The service sends article titles, summaries, company names, categories, and detailed content to a third-party AI endpoint, but this file shows no consent, disclosure, minimization, or policy gating before export. If the news items contain licensed, confidential, embargoed, or personal data, this creates a real data-governance and privacy risk through external transmission.

Medium
Category
Not specified by scanner
Confidence
95% confidence
Finding

The prompt explicitly requires Chinese output for the title, summary, and reasoning fields, using phrases such as 中文标题, 中文摘要, and 用一句简短中文说明判断理由. This enforces a specific language/locale without any visible opt-in or documented justification in the file, which matches the locale policy violation criteria.

Confidence
95% confidence
Finding

The class docstring specifies fixed Chinese output structure and labels, including Chinese section names, without indicating any user opt-in or locale selection. This is a natural-language locale policy concern because the skill appears to enforce a specific language rather than offering a choice or documenting a justified regional constraint.

Confidence
90% confidence
Finding

The import and later use of normalize_to_shanghai indicates the skill forces all timestamps into a Shanghai locale/timezone context. Under the policy, forcing a specific locale without user choice or a clearly documented region-specific justification is a natural-language policy concern.

Confidence
94% confidence
Finding

The class docstring states that for domestic sources, only news about companies whose country/region is China will be retained, and the implementation enforces that rule. This is a natural-language locale/policy constraint that forces a specific regional treatment without indicating any user choice, opt-in, or clearly documented compliance justification in this file.

Confidence
97% confidence
Finding

This service is hardcoded to translate all non-Chinese content into Chinese and then overwrite the main item fields with the Chinese version, with no user choice or opt-in. That is primarily a product and trust/privacy issue rather than a classic exploit, but it can cause unintended data handling, loss of original presentation, and surprising behavior in downstream systems.

Missing User Warnings

Medium
Category
Not specified by scanner
Confidence
95% confidence
Finding

The DeepTranslatorBackend sends supplied text to an external translation service, which can expose titles, summaries, and article content to a third party without any disclosure, consent, or data-classification check in this component. In a news-ingestion pipeline this may leak sensitive or proprietary content and create compliance/privacy issues even if the developer's intent is functionality rather than harm.

Content

Unbounded Output

Medium
Category
Output Handling
Confidence
75% confidence
Finding

Output size or generation rate is not bounded. Unbounded output enables denial-of-service through resource exhaustion, log flooding, or context-window stuffing.

Unbounded Output

Medium
Category
Output Handling
Confidence
75% confidence
Finding

The service translates cleaned_content with no length cap, and cleaned_content may be derived from raw article body content. Large attacker-controlled inputs could trigger excessive memory, CPU, API cost, or latency in the translation backend and downstream hashing/storage pipeline, creating a denial-of-service or cost-amplification risk.

Confidence
95% confidence
Finding

The config sets project.language to zh, which indicates the skill is configured to operate in a specific language by default. Under the policy rule, forcing a language/locale without user opt-in is a natural-language policy concern, and this file does not show any alternative language selection or opt-in mechanism.

Confidence
95% confidence
Finding

The file emits user-facing status messages, logs, filenames, and generated content instructions in Chinese throughout the workflow, including startup messages, warnings, summaries, and final console output. Because there is no visible user opt-in or documented justification for enforcing Chinese, this appears to violate the language/locale policy for natural-language behavior.

Context-Inappropriate Capability

Medium
Category
Not specified by scanner
Confidence
94% confidence
Finding

The code transmits collected news items to an external AI service via AISummaryService using a configured API key and base URL, but the file provides no consent check, data minimization, redaction, or policy gate before third-party processing. Because the pipeline aggregates scraped content and company-related metadata, this can create data governance, confidentiality, and compliance exposure if sensitive or licensed content is forwarded off-platform.

Content

No source excerpt is available for this finding.

Natural-Language Policy Violations

Medium
Category

Confidence
93% confidence
Finding

The file contains natural-language comments, exception text, CLI help strings, and return messages in Chinese, which imposes a specific language on users. There is no opt-in, alternate locale, or documentation indicating that the skill is intentionally region-specific, so this is a language/locale policy concern.
