GEO Competitor Scanner

• Outcome: Review
• Latest audit: Sep 11, 2026 · 1:48 AM UTC
• Version: 1.0.0

Overview

This is a legitimate competitor-website scanner, but it can make unrestricted network requests to user-supplied targets and should be reviewed before use.

Install only if you are comfortable with a local script making outbound requests to every domain you provide. Use it with explicit public competitor domains only, avoid inputs from untrusted text, run it in a restricted environment, and prefer pinned dependency installation before executing the scanner.

Vulnerability Patterns

• Insecure Dependencies: Introduces malicious components through unsafe dependency sources
• Insecure Skill Coding Practices: Finds exploitable flaws such as hardcoded secrets or command injection
• Skill Instruction Hijacking: Alters the agent's session goals or safety constraints when the skill loads
• Agent Memory Poisoning: Writes attacker-controlled rules into memory that affect later sessions
• Remote Payload Retrieval and Execution: Fetches external code whose behavior can change after review

Vulnerability Type: Server-Side Request Forgery through unrestricted user-controlled domains and redirects
Risk Level: High

Vulnerable Code:

python

class GEOScanner:
    """Scan website for GEO signals."""
    
    def __init__(self, domain, timeout=10):
        self.domain = domain.replace('https://', '').replace('http://', '').rstrip('/')
        self.base_url = f"https://{self.domain}"
        self.timeout = timeout
        self.results = {
            'domain': self.domain,

            'entity': {},
            'citation': {}
        }

        url = urljoin(self.base_url, path)
        try:
            resp = requests.get(url, timeout=self.timeout, allow_redirects=True)
            return resp
        except Exception as e:
            return None

python

domains = [args.brand] + [c.strip() for c in args.competitors.split(",")]

results = []
for domain in domains:
    scanner = GEOScanner(domain)
    result = scanner.run_full_scan()
    results.append(result)

Technical Analysis

Values supplied through --brand and --competitors are directly converted into outbound HTTPS request targets. The code does not validate that a supplied hostname resolves to a publicly routable address. It therefore permits loopback, private, link-local, reserved, and internal DNS destinations.

The request also uses allow_redirects=True. Even if an initial hostname were validated as public, an attacker-controlled public endpoint could redirect the scanner to an internal address. No validation is performed for redirect destinations or after DNS resolution.

The scanner sends requests to numerous fixed paths, including /, /llms.txt, /robots.txt, ` ...[truncated 1719 chars]

Remediation Suggestions

1. Parse targets using urllib.parse rather than modifying strings with replace().
2. Accept only well-formed hostnames with an explicitly permitted scheme, preferably HTTPS.
3. Resolve every hostname before connecting and reject all loopback, private, link-local, multicast, reserved, and unspecified IPv4 and IPv6 addresses using Python's ipaddress module.
4. Disable automatic redirects or validate the hostname and resolved addresses of every redirect destination before following it.
5. Guard against DNS rebinding by ensuring the address used for the connection remains within the validated set.
6. Apply an outbound firewall or proxy allowlist so the scanner can reach only public web destinations.
7. Reject embedded credentials, unexpected ports, malformed hostnames, and ambiguous URL syntax.
8. Add tests covering loopback addresses, RFC 1918 networks, IPv6 local addresses, internal DNS names, encoded IP representations, and public-to-private redirects.
9. Return a clear validation error instead of silently treating blocked destinations as failed scans.

Vulnerability Details

File Location: scripts/scan_competitors.py, lines 10-16
Vulnerability Type: Unsafe dependency acquisition without version or integrity constraints
Risk Level: Medium

Vulnerable Code:

python

try:
    import requests
    from bs4 import BeautifulSoup
except ImportError:
    print("Error: pip install requests beautifulsoup4")
    sys.exit(1)

Technical Analysis

When dependencies are unavailable, the script instructs the operator to install requests and beautifulsoup4 without exact versions, cryptographic hashes, a lockfile, or a specified trusted package index.

As a result, the command resolves mutable package releases from the environment's configured Python package repository at installation time. The project does not provide a requirements file or other reviewed dependency manifest that would make installations reproducible and integrity-checked.

Although the package names shown are established package names and no malicious dependency is embedded in the project, the installation process remains exposed to compromised future releases, repository or mirror compromise, unsafe index configuration, and unreviewed breaking changes.

Attack Path

1. The scanner is executed in an environment where one or both dependencies are missing.
2. The script prints the unpinned installation command.
3. A user or Agent runs that command using its configured package index.
4. Package resolution selects the latest matching releases without checking project-approved versions or hashes.
5. If a selected package, package release, index, or mirror has been compromised, attacker-controlled installation or runtime code executes locally.
6. That code receives the privileges and environment access of the user performing the installation or running the scanner.

Successful supply-chain exploitation could execute code with the privileges of the installin ...[truncated 384 chars]

Remediation

Remediation Suggestions

1. Add a reviewed dependency manifest with exact versions for all direct and transitive dependencies.

2. Include cryptographic hashes and install with a command such as:

   bash

   python -m pip install --require-hashes -r requirements.txt
   

3. Generate and maintain a lockfile using a dependency-management tool that supports reproducible resolution.

4. Configure installations to use an explicitly trusted package index and authenticated internal mirror where appropriate.

5. Review dependency updates through a controlled change process rather than resolving unrestricted latest versions at runtime.

6. Run software composition analysis and vulnerability checks against the locked dependency set.

7. Prefer installation in an isolated virtual environment with minimal filesystem, credential, and network privileges.

8. Replace the generic installation message with a reference to the project's locked installation procedure.

Undeclared Tool Scope

Medium

• Category: MCP Least Privilege
• Confidence: 93% confidence

Finding

The skill instructs users to run local Python scripts that perform network access against competitor domains and write reports/results to disk, but the manifest declares no explicit tool scope or permission boundaries. In an agent environment, this mismatch can cause overbroad or implicit access, making it harder to enforce least privilege and increasing the risk of unintended network targeting or file writes.

Content

No source excerpt is available for this finding.

Vague Triggers

Medium

• Category: Not specified by scanner
• Confidence: 91% confidence

Finding

The description uses very broad triggers like 'whenever the user mentions scanning competitor GEO strategies' and related competitor-analysis phrasing, which could cause the skill to activate for ordinary marketing or research requests without the user intending network scans. Because this skill can lead to external site access and file generation, overbroad invocation increases the chance of unexpected data collection or actions being taken in the wrong context.

Description-Behavior Mismatch

Medium

• Category: Not specified by scanner
• Confidence: 88% confidence

Finding

The manifest describes analyzing competitor GEO strategies, AI citation signals, and benchmarking performance, which implies substantive comparative analysis of how competitors win citations. In practice, the citation scan just checks whether a few fixed paths like /compare, /about, and /what-is return a response, and the rest of the scan relies on basic counts from homepage structure and schema extraction.

Description-Behavior Mismatch

Medium

• Category: Not specified by scanner
• Confidence: 92% confidence

Finding

The reporting function formats raw scan outputs into a markdown table and score summary, but it does not compute missing capabilities relative to competitors or derive recommendations. That is a semantic mismatch with the stated purpose of identifying strategic gaps and opportunities.
