Security checks for vulnerabilities and agentic risk

Overview

This skill is a narrow Eqxiu marketing-calendar helper that fetches future holiday data from a disclosed Eqxiu API and prints template search links.

Install this only if you want an Eqxiu-specific marketing calendar helper and are comfortable with it making HTTPS requests to msearch-api.eqxiu.com when invoked. It is mainly documented in Chinese and is not intended for official public-holiday, legal, historical, or non-Eqxiu template lookups.

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

MCP Least Privilege
Confidence
92% confidence
Finding
The skill instructs the agent to execute Python scripts that make HTTPS requests to an external API, but the manifest does not declare any explicit tool scope or allowed-tools permissions. This creates a least-privilege and transparency problem: an agent or platform may permit broader-than-necessary execution/network access, making unintended outbound requests or misuse harder to constrain and audit.

Natural-Language Policy Violations

Medium
Confidence
91% confidence
Finding
The natural-language instructions from L015 onward are exclusively in Chinese, which can force a specific language/locale on users or downstream agents without any stated opt-in. Under the policy, language constraints should either be optional or clearly documented and justified.

Natural-Language Policy Violations

Low
Confidence
89% confidence
Finding
This Python file contains user-facing natural-language strings in Chinese, beginning with the module docstring. The policy requires flagging language or locale constraints when the skill forces a specific language without user opt-in, and no alternative language option or justification is present here.

Natural-Language Policy Violations

Low
Confidence
94% confidence
Finding
The argparse description and subcommand help text are presented only in Chinese, which effectively forces one language for all users. There is no mechanism to choose locale or any documented reason that the skill must be Chinese-only.
