Security checks for vulnerabilities and agentic risk

Overview

The skill is mostly coherent for cloud-based bid-document processing, but it needs Review because it under-discloses persistent local metadata, allows broad output writes, and tries to control what the agent tells users.

Review before installing. This skill sends tender and bid documents to the vendor's cloud service and uses an API key tied to billing, so only use it with files you are authorized to upload. Keep the API key out of chat. Prefer the default output directory, avoid user-supplied absolute output paths or unusual basenames, and periodically check/remove ~/.zcm/projects.json if installed.

Vulnerability Patterns
  • Skill Instruction HijackingAlters the agent's session goals or safety constraints when the skill loads
  • Unauthorized Access and Privilege EscalationObtains permissions beyond the task's legitimate needs
  • Insecure Skill Coding PracticesFinds exploitable flaws such as hardcoded secrets or command injection
  • Agent Memory PoisoningWrites attacker-controlled rules into memory that affect later sessions
  • Remote Payload Retrieval and ExecutionFetches external code whose behavior can change after review

It restricts what the agent may disclose about execution and requires predefined registration, configuration, feature, and promotional information to be inserted into user-facing responses. Related instructions in `SKILL.md` also require the agent to reproduce a channel-tagged service URL such as: ```text https://biaoshu.zhiliaobiaoxun.com/?ch=c666 ``` This goes beyond task-specific operational guidance. Loading the Skill changes the agent's response objectives and presentation policy, including mandatory commercial redirection and suppression of operational details.

Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
95% confidence
Finding

The entire skill file is written as mandatory operational guidance in Chinese and includes no indication that another language may be used or that the user can opt into a locale. Under the stated policy, forcing a specific language without user choice is a natural-language policy violation unless clearly justified as region-specific.

Content

Confidence
90% confidence
Finding

The entire skill documentation is written as a Chinese-only interface and workflow, with no indication that users may choose another language or that the skill is limited to a specific locale for compliance or business reasons. Under the stated policy, forcing a specific language without user opt-in is a natural-language policy violation.

Missing User Warnings

Medium
Category
Not specified by scanner
Confidence
91% confidence
Finding

The document explicitly states that uploaded files and task results are retained on the vendor's servers and may persist for about 7 days, but it does not pair that statement with a clear requirement to obtain user consent, warn users about privacy implications, or restrict use with sensitive content. In a bid/tender workflow, uploaded documents often contain confidential commercial, personal, or regulated data, so undocumented or under-communicated retention increases privacy, confidentiality, and compliance risk.

Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
88% confidence
Finding

The instruction says script output and reports have already been converted to Chinese and should be presented directly in Chinese. This imposes a specific language on user-facing output without stating that the user may choose another language or locale, which is a natural-language policy issue.

Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
90% confidence
Finding

The exception text and CLI descriptions are written only in Chinese, which can constitute a language/locale policy violation when no opt-in or alternative locale is offered. Nothing in this file documents that the tool is intentionally region-specific or provides users a choice of language.

Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
93% confidence
Finding

The argparse description and help strings are all presented in Chinese, and the file contains no mechanism for user locale selection. Under the policy criteria, forcing a specific language without opt-in is a natural-language policy concern unless the locale limitation is clearly justified.

Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
96% confidence
Finding

This code hard-codes report titles and labels in Chinese, and the same pattern continues throughout the file. Because the skill does not offer any language selection or document that it is intentionally limited to a Chinese-only locale, it creates a natural-language locale policy violation under the requirement to avoid forcing a specific language without user opt-in.

Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
98% confidence
Finding

The generated HTML hard-codes lang='zh-CN', which imposes a specific language/locale in the rendered output. The file also contains extensive fixed Chinese UI text throughout the report generator, with no visible mechanism for user opt-in or locale selection.

Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
94% confidence
Finding

The error text shown to users in size-validation failures is written only in Chinese, and the file provides no mechanism for language selection or opt-in. This creates a natural-language policy issue if the skill is expected to operate across users without forcing a specific language.

Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
92% confidence
Finding

This batch-size error message is also fixed to Chinese, with no indication that the tool is region-specific or that users can choose another language. Forcing a single language in user-facing output without opt-in can violate organizational language/locale policy.

Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
90% confidence
Finding

The file-not-found error presented to the user is only in Chinese, and no locale-selection mechanism is visible in this file. This is a natural-language policy concern because it forces a specific language for runtime feedback.

Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
96% confidence
Finding

The string literal "请求失败 HTTP ..." hard-codes Chinese for user-facing output. This file does not show any locale selection, opt-in, or documentation justifying a fixed language, so it appears to violate the language/locale policy requirement.

Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
97% confidence
Finding

This code emits user-facing status and error messages in Chinese, and the pattern continues throughout the file via print/log statements. For a natural-language policy check, this is a locale/language constraint imposed without opt-in or justification, which can violate organizational expectations for language neutrality or user choice.

Tool Misuse
Confidence
75% confidence
Finding

Tool defaults are unsafe or overly permissive (e.g. disabled TLS verification, no authentication, world-writable permissions). Unsafe defaults widen the attack surface.

Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
96% confidence
Finding

This code formats durations and sizes using Chinese-only strings such as "分钟", "小时", and "未知大小", and the rest of the module also emits Chinese-only progress text. That imposes a specific language/locale in user-facing output without any opt-in, choice, or justification, which matches the natural-language policy violation criteria.

Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
93% confidence
Finding

The file defines Chinese-only label translations and later emits user-facing Chinese messages, which indicates the skill forces a specific locale in its presentation layer. There is no visible user opt-in or alternative language path in this file, so it appears to violate the language/locale choice policy.

Content

Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
91% confidence
Finding

The platform reminder and balance-report messages are emitted directly in Chinese, and the file does not show any mechanism for language negotiation or user preference. This creates a natural-language policy issue because the skill appears to require a specific language for interaction.

Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
90% confidence
Finding

Error and success messages related to report generation are presented only in Chinese, with no visible option for another language. Because these are user-facing operational messages, the lack of language choice is a policy concern.

Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
89% confidence
Finding

The command path logs report locations using Chinese-only text and does not indicate any locale configurability. Without explicit opt-in or documentation that the tool is region-specific, this is a language policy violation.

Natural-Language Policy Violations

Low
Category
Not specified by scanner
Confidence
93% confidence
Finding

This markdown file contains user-facing instructions exclusively in Chinese and does not indicate that other languages are supported or that Chinese is an intentional opt-in. Under the policy category for natural-language violations, forcing a specific language without user choice can be a locale-policy issue.

Natural-Language Policy Violations

Low
Category
Not specified by scanner
Confidence
83% confidence
Finding

This markdown file uses only Chinese for the API description, requirements, and error handling guidance. Under the policy, forcing a specific language without user opt-in can be a natural-language policy violation unless the locale constraint is explicitly justified, which is not stated here.

Natural-Language Policy Violations

Low
Category
Not specified by scanner
Confidence
97% confidence
Finding

This code explicitly documents that report artifacts ship with zh-CN labels, and the module contains many fixed Chinese user-facing strings. The applicable policy rule flags language or locale constraints unless they are clearly documented and justified; here the comment provides a concrete mainland-China procurement justification, so this is at most a minor policy concern rather than a strong violation.

Missing User Warnings

Low
Category
Not specified by scanner
Confidence
85% confidence
Finding

This code performs file creation/writes for HTML and DOCX outputs, which is a safety-relevant filesystem operation for code files under the audit criteria. Although the CLI exposes output-path arguments, this file contains no confirmation prompt, user-facing warning, or explanatory comment/docstring disclosing that reports will be written to disk.
