PostKing · Landing Pages

Security checks for vulnerabilities and agentic risk

Overview

This is a disclosed PostKing landing-page management skill, with live publishing and domain actions that users should treat carefully but no evidence of hidden or malicious behavior.

Install this only if you want the agent to manage PostKing landing pages. Before allowing publish, unpublish, delete, rename, restore, or domain-removal actions, confirm the exact page, side page, version, or domain and review the preview or current state first.

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
  • Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
  • Data ExfiltrationExternal Transmission, Env Variable Harvesting, File System Enumeration
  • 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

Finding

The skill documents publish_landing_page and deletion-capable lifecycle actions as routine steps without a consistent requirement to confirm destructive or externally visible changes with the user first. In an agent setting, that can lead to unintended publication of draft content or irreversible content removal when the model interprets an editing request too broadly.

Finding

The custom-domain section notes that delete_domain removes a domain and that connected pages are unlinked, but it does not present this as a prominent safety warning or require confirmation before suggesting the action. In practice, an agent could remove a live domain during cleanup or troubleshooting, causing immediate loss of intended public routing for live landing pages.
