Security checks for vulnerabilities and agentic risk

Overview

This skill is a disclosed Chinese-language WeChat article analysis helper and does not show hidden, destructive, persistent, or credential-seeking behavior.

Install this if you want Chinese-language WeChat article diagnostics. Be mindful that giving it a URL may cause that page to be fetched, and verify any health, finance, or other expert-domain content separately because the skill focuses on communication effectiveness, not factual certification.

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
Vulnerability Patterns

Findings (5)

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
95% confidence
Finding

The trigger list includes broad, generic phrases such as '文章分析' and '运营优化' that can match many ordinary user requests outside the intended public-account/article-diagnosis scope. Overbroad activation can cause the skill to intercept unrelated conversations, increasing the chance of unintended tool use, misleading responses, or inappropriate handling of user content.

Finding

SQP-3 applies to all file types and includes language or locale policy violations. This file presents all instructions and examples only in Chinese, with no indication that the skill is region-specific or that users can opt into this language, which may violate a policy requiring language choice or justification.

Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
92% confidence
Finding

This markdown file contains user-facing natural language exclusively in Chinese, beginning with the title at L001 and continuing throughout the rubric. Under the policy, forcing a specific language without user opt-in is a locale/language policy violation unless the restriction is clearly documented and justified, which is not present here.

Natural-Language Policy Violations

Medium
Category

Confidence
95% confidence
Finding

The file title and all instructional content are written exclusively in Chinese, which effectively forces a specific language/locale for use of the skill content. There is no indication that users may choose another language, nor any documented region-specific justification for the restriction.

Missing User Warnings

Low
Category
Not specified by scanner
Confidence
83% confidence
Finding

The skill instructs the agent to fetch arbitrary third-party article URLs but does not warn users that external content will be retrieved and processed. This can create privacy and expectation issues, and in a broader agent environment may increase exposure to untrusted remote content without clear user consent or boundary-setting.
