Security audit

Sovereign Seo Audit

Security checks for vulnerabilities and agentic risk

Overview

This is a coherent SEO audit skill with disclosed website/code/content analysis behavior and no evidence of hidden execution, persistence, or credential theft.

Install only if you want your agent to perform SEO audits on URLs, repositories, HTML, or content you provide. Approve external website checks and competitor analysis deliberately, and do not submit staging, internal, confidential, or non-owned URLs to IndexNow, Search Console, or similar 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
  • Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
  • Data ExfiltrationExternal Transmission, Env Variable Harvesting, File System Enumeration
  • Trigger AbuseOverly Broad Trigger, Shadow Command Trigger, Keyword Baiting Trigger
  • Privilege EscalationExcessive Permissions, Sudo/Root Execution, Credential Access
  • Supply ChainUnpinned Dependencies, External Script Fetching, Obfuscated Code

Hidden Instructions

High
Category
Prompt Injection
Content
**Required meta tags:**
```html
<!-- Title tag: 50-60 characters, unique per page, primary keyword near start -->
<title>Primary Keyword - Secondary Keyword | Brand Name</title>

<!-- Meta description: 150-160 characters, includes CTA, unique per page -->
Confidence
70% confidence
Finding
Hidden instructions were detected in comments or invisible text. These could contain malicious directives. Manual review is recommended.

Vague Triggers

Medium
Confidence
92% confidence
Finding
The usage examples are broad enough that a host agent could trigger this skill from ordinary user requests like 'audit this website' or 'what should I fix first?' without clear boundaries. Over-broad activation increases the chance of unintended URL fetching, code inspection, or competitor-site analysis in contexts where the user did not explicitly consent to those actions.

External Transmission

Medium
Category
Data Exfiltration
Content
### IndexNow (Bing, Yandex, Seznam, Naver)
```bash
curl -X POST "https://api.indexnow.org/indexnow" \
  -H "Content-Type: application/json" \
  -d '{
    "host": "example.com",
Confidence
82% confidence
Finding
Referencing the IndexNow endpoint in direct submission instructions reinforces a workflow that sends site URLs to an external service. The risk is contextual: the data is not inherently secret, but in some environments unpublished URLs, staging domains, or internal paths could be exposed if a user follows the guidance blindly.

Missing User Warnings

Low
Confidence
87% confidence
Finding
The README says the skill can evaluate websites, codebases, and competitor sites, but it does not disclose that this may involve accessing external URLs or inspecting supplied source content. That omission can mislead users and orchestration layers about data access behavior, creating privacy, consent, and unexpected network-action risks.

Missing User Warnings

Low
Confidence
85% confidence
Finding
The skill recommends submitting URLs to external indexing services and search consoles without an explicit user warning or consent checkpoint. While the section is instructional rather than self-executing, it could still lead an agent or user to transmit site metadata to third parties without understanding privacy, ownership, or disclosure implications.
