Security checks for vulnerabilities and agentic risk

Overview

This is a straightforward Unsplash API reference skill with disclosed credential setup and expected calls to Unsplash.

Install only if you are comfortable creating an Unsplash developer access key and letting the agent make Unsplash API requests with your search terms. Prefer the environment variable option for temporary use, or keep the config file permission-restricted as shown.

A.I.G

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

Session Persistence

## Setup & Authentication

### Get your Access Key
1. Create account at https://unsplash.com/developers
2. Register a new application
3. Copy your **Access Key** (starts with your app name)
Confidence
60% confidence
Finding
Skill establishes unauthorized persistence across sessions via cron jobs, startup scripts, or state files. Session persistence allows an attacker to maintain access beyond the current interaction.

Sudo/Root Execution

Medium
Category
Privilege Escalation
Content
```bash
mkdir -p ~/.config/unsplash
echo "YOUR_ACCESS_KEY" > ~/.config/unsplash/access_key
chmod 600 ~/.config/unsplash/access_key
```

Or set environment variable:
Confidence
80% confidence
Finding
Commands invoke sudo or root privileges. Verify this elevated access is necessary and justified.
