Security checks for vulnerabilities and agentic risk

Overview

This skill openly aims to publish daily AI opinion posts, but it relies on unattended scheduling and GitHub pushes that are not tightly scoped or review-gated in the artifact.

Install only if you intentionally want an unattended daily job that can generate, commit, and push public site content. Before enabling it, review the referenced source script, confirm it stages only the intended _posts file, use a dedicated Git branch or token with minimal permissions, and make launchd scheduling and automatic push explicitly opt-in.

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
  • Supply ChainUnpinned Dependencies, External Script Fetching, Obfuscated Code

Scope Creep

High
Category
Not specified by scanner
Confidence
97% confidence
Finding

The documented GitHub commit/push behavior exceeds the declared permissions of only http.request and file.write, indicating a mismatch between advertised capability and actual side effects. Hidden or undeclared publication behavior undermines permission transparency and could allow the skill to alter or publish repository content without users accurately understanding its access level.

Missing User Warnings

Confidence
91% confidence
Finding

The description presents the skill as a simple content generator but omits a clear warning that it writes into a repository and automatically commits and pushes changes on a daily schedule. In context, the daily unattended execution makes this more dangerous because it can repeatedly publish unwanted or manipulated content without timely human review.

Context-Inappropriate Capability

Medium
Category
Not specified by scanner
Confidence
94% confidence
Finding

The skill documentation states it will auto-commit and push to GitHub, which goes beyond the narrow user-facing purpose of generating a short opinion post. That creates an autonomous external side effect on a repository, increasing the risk of unintended content publication or repository changes without clear user awareness or necessity.
