Content Auto Poster

Security checks for vulnerabilities and agentic risk

Overview

This skill is a straightforward Chinese-language content auto-poster, with public posting behavior that is visible and aligned with its purpose.

Install only if you intend to publish content to the listed external platforms. Review the target platforms and scheduled time before use, and do not provide confidential, unpublished, regulated, or internal content unless you want it posted publicly or sent to those services.

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

Natural-Language Policy Violations

Confidence
93% confidence
Finding

The skill metadata and entire user-facing description are presented only in Chinese, indicating a fixed language/locale experience. There is no statement that the skill is China-specific or that users may choose another language, which conflicts with the requirement to avoid forcing a specific language without opt-in.

Missing User Warnings

Confidence
95% confidence
Finding

The skill is explicitly designed to take user-provided content and publish it to third-party platforms, but it does not warn users that their data will be transmitted externally. This creates a real privacy and safety risk because users may provide sensitive, unpublished, or internal content without understanding it will be sent outside the local environment to multiple services.
