Security audit

SEO Content Optimizer

Security checks for vulnerabilities and agentic risk

Overview

The skill is mostly a markdown-only SEO helper, but one example encourages inventing personal work experience to make public content seem more credible.

Review this skill before installing if you plan to use it for public posts. Its SEO advice is otherwise bounded, but users should avoid applying the example that invents personal experience, credentials, testimonials, or lived experience.

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
  • Excessive AgencyUnrestricted Tool Access, Autonomous Decision Making, Scope Creep
  • Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
  • Data ExfiltrationExternal Transmission, Env Variable Harvesting, File System Enumeration
  • Privilege EscalationExcessive Permissions, Sudo/Root Execution, Credential Access

Natural-Language Policy Violations

Medium

Not specified by scanner
Confidence
95% confidence
Finding

This markdown file presents the skill usage, requests, and recommendations exclusively in Chinese, which effectively forces a specific language for users. The file does not mention that the skill is Chinese-only, nor does it offer any opt-in or alternative language behavior.

Context-Inappropriate Capability

Medium

Confidence
97% confidence
Finding

The Zhihu example explicitly suggests an opening that claims '作为一个从零基础到现在工作 5 年的程序员' to establish credibility, even though this is presented as a reusable optimization template rather than verified user-provided biographical data. That encourages deceptive impersonation and fabrication of credentials, which can mislead readers, violate platform trust rules, and normalize dishonest content generation.

Natural-Language Policy Violations

Confidence
95% confidence
Finding

The README consistently presents all instructions, examples, and usage guidance only in Chinese. Under the stated policy, forcing a specific language without user opt-in is a natural-language policy violation unless the locale constraint is explicitly documented and justified, which is not present here.
