Typecho Post Publisher

Security checks for vulnerabilities and agentic risk

Overview

This skill is a coherent Typecho blog publishing helper, but it uses stored credentials to publish or edit live posts without explicit confirmation safeguards.

Review this before installing if the blog has real readers or business impact. Only configure credentials you are comfortable letting the agent use, and require an explicit confirmation step before login, publishing, or saving edits.

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
  • Trigger AbuseOverly Broad Trigger, Shadow Command Trigger, Keyword Baiting Trigger
  • Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
  • Privilege EscalationExcessive Permissions, Sudo/Root Execution, Credential Access
  • Supply ChainUnpinned Dependencies, External Script Fetching, Obfuscated Code

Vague Triggers

Confidence

Finding

The skill description includes broad scenarios such as helping write and publish or edit existing posts, which can match ordinary content-assistance requests and trigger a high-impact action skill too easily. Because this skill can authenticate and modify a live blog, ambiguous activation increases the chance of unintended publication or edits without sufficiently explicit user intent.

Missing User Warnings

Confidence
95% confidence
Finding

The skill is designed to use stored blog credentials to log in and publish or edit content, but it does not require an explicit warning or confirmation before performing authenticated, state-changing actions. This creates a meaningful risk of unauthorized or accidental publication, modification of existing content, and misuse of privileged access if the skill is invoked under ambiguous circumstances.
