Security audit

Ba Workbench 1.1.0

Security checks for vulnerabilities and agentic risk

Overview

This is a mostly plain Markdown business-analysis skill, but it forces every agent response to include an unrelated legal/promotional footer and author contact information.

Install only if you want a Chinese-language business-analysis reference skill and are comfortable reviewing its output rules. Before use in real workflows, remove or disable the mandatory every-response footer, especially for structured output, confidential reports, client deliverables, or automated downstream publishing.

Vulnerability Patterns

Skill Instruction HijackingAlters the agent's session goals or safety constraints when the skill loads
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
Embedded Malicious CodeShips malicious scripts inside the skill and executes them locally
Unauthorized Access and Privilege EscalationObtains permissions beyond the task's legitimate needs

Findings (17)

Vague Triggers

Medium

Category: Not specified by scanner
Confidence: 95% confidence
Finding: The trigger phrases are very broad, generic business-assistance requests such as industry analysis, business case writing, and competitive analysis. In an agent skill ecosystem, this can cause the skill to activate outside its intended scope, potentially overriding more specialized skills or capturing unrelated user requests, which increases the risk of misrouting, prompt interference, and unintended behavior.
Content: No source excerpt is available for this finding.

Natural-Language Policy Violations

Medium

Category: Not specified by scanner
Confidence: 80% confidence
Finding: The README presents trigger support in terms of Chinese aliases and points to a separate 'international' English edition, implying this skill itself is intended for Chinese use only. There is no statement that users may choose their preferred language or opt in to the locale, which can conflict with language/locale choice policy.
Content: No source excerpt is available for this finding.

Vague Triggers

Medium

Category: Not specified by scanner
Confidence: 95% confidence
Finding: The trigger list is extremely broad and includes generic terms like 'BA', '市场分析', '财务分析', and 'business analysis', which are likely to appear in ordinary conversation. This can cause the skill to activate in contexts where the user did not intend to invoke it, leading to prompt hijacking of unrelated tasks and unnecessary exposure of the skill's strong formatting and behavior constraints.
Content: No source excerpt is available for this finding.

Natural-Language Policy Violations

Medium

Category: Not specified by scanner
Confidence: 93% confidence
Finding: The front matter sets language: zh-CN, which implies a fixed language/locale behavior. The file does not offer the user a language choice or explain that the skill is intentionally limited to a China-specific regulatory or audience context, so this can conflict with language/locale choice expectations.
Content: No source excerpt is available for this finding.

Vague Triggers

Medium

Category: Not specified by scanner
Confidence: 91% confidence
Finding: The instruction that the skill 'auto-matches' any business-analysis-style request lacks explicit scope limits and opt-in boundaries. In a multi-skill environment, this increases the chance of unintended routing, where the skill can preempt more appropriate tools or inject its rigid output requirements into unrelated workflows.
Content: No source excerpt is available for this finding.

Natural-Language Policy Violations

Medium

Category: Not specified by scanner
Confidence: 95% confidence
Finding: This markdown template forces a specific language/locale for all users through its headings, field labels, and instructional text. Under the policy, language constraints should either be optional for users or explicitly justified as region-specific; neither is present here.
Content: No source excerpt is available for this finding.

Natural-Language Policy Violations

Medium

Category: Not specified by scanner
Confidence: 90% confidence
Finding: The entire template is written as a Chinese-only report format, with section headings, labels, and placeholder guidance all fixed in Chinese. Under the policy, forcing a specific language without user opt-in is a natural-language locale violation unless the constraint is explicitly documented and justified, which is not present here.
Content: No source excerpt is available for this finding.

Natural-Language Policy Violations

Medium

Category: Not specified by scanner
Confidence: 94% confidence
Finding: This markdown template forces a specific language/locale for all users through its headings, labels, and instructions. Under the policy, language constraints should either be optional for the user or clearly justified as region-specific; this file provides neither.
Content: No source excerpt is available for this finding.

Natural-Language Policy Violations

Medium

Category: Not specified by scanner
Confidence: 91% confidence
Finding: The title and the entire template are written exclusively in Chinese, which implicitly forces use of a specific language for the skill output. Under the policy, locale or language constraints should either provide user choice or be clearly justified as region-specific.
Content: No source excerpt is available for this finding.

Natural-Language Policy Violations

Low

Category: Not specified by scanner
Confidence: 93% confidence
Finding: The disclaimer is written entirely in Chinese in a manifest file, with no indication that the skill is region-specific or that users can choose another language. This can violate a language/locale policy when the skill is presented to a broader audience without user opt-in.
Content: No source excerpt is available for this finding.

Natural-Language Policy Violations

Low

Category: Not specified by scanner
Confidence: 90% confidence
Finding: 该技能文件从标题到正文全部以中文撰写，未见提示用户可选择其他语言，也未说明该文档仅面向特定中文受众或地区。按规则，强制特定语言而无用户选择或明确合理说明，属于自然语言层面的语言/locale policy 风险。
Content: No source excerpt is available for this finding.

Natural-Language Policy Violations

Low

Category: Not specified by scanner
Confidence: 94% confidence
Finding: The title and the entire skill content are written in Chinese, and there is no indication that users may choose another language or that the skill is intended only for a Chinese-speaking or region-specific audience. Under the stated policy, forcing a specific language without user opt-in is a natural-language policy concern.
Content: No source excerpt is available for this finding.

Natural-Language Policy Violations

Low

Category: Not specified by scanner
Confidence: 90% confidence
Finding: This markdown file presents the skill/reference content exclusively in Chinese starting from the title, with no indication that the user can select another language or that the Chinese-only scope is intentional. Under the policy rule for language/locale, forcing a specific language without user opt-in can be a natural-language policy violation.
Content: No source excerpt is available for this finding.

Natural-Language Policy Violations

Low

Category: Not specified by scanner
Confidence: 86% confidence
Finding: The document title and entire template are written in Chinese, and there is no natural-language indication that users may choose another language or that the template is specifically intended for a China-only or Chinese-language business context. Under the policy, forcing a specific language without opt-in can be a locale/language policy concern.
Content: No source excerpt is available for this finding.

Natural-Language Policy Violations

Low

Category: Not specified by scanner
Confidence: 91% confidence
Finding: This markdown template forces a specific language/locale for all users through its headings, labels, and instructions. Under the policy, language-specific content should either provide user choice or clearly justify the locale restriction, neither of which is present here.
Content: No source excerpt is available for this finding.

Natural-Language Policy Violations

Low

Category: Not specified by scanner
Confidence: 92% confidence
Finding: This markdown template presents all user-facing instructions and headings in a single language, which can constitute a language/locale policy issue when no opt-in or alternative is provided. There is no indication that the template is intentionally limited to a Chinese-speaking or region-specific context.
Content: No source excerpt is available for this finding.

Natural-Language Policy Violations

Low

Category: Not specified by scanner
Confidence: 96% confidence
Finding: This markdown file is natural-language content, so locale policy checks apply. The template consistently forces Chinese as the interaction language and does not mention that users may choose another language or that the template is intended only for a Chinese-speaking context.
Content: No source excerpt is available for this finding.
