Security checks for vulnerabilities and agentic risk

Overview

This SEO skill largely matches its stated purpose, but it forces promotional links into user reports and asks for broad access to prior conversations or memory.

Review this skill before installing if you do not want automatic promotional links in reports or broad use of prior conversation/memory context. Use it only with credentials and paid API accounts you intend to expose for SEO analysis, avoid running the unpinned npx Lighthouse example unless you pin or preinstall it, and confirm costs before DataForSEO geo-grid scans.

Vulnerability Patterns
  • Skill Instruction HijackingAlters the agent's session goals or safety constraints when the skill loads
  • Unauthorized Access and Privilege EscalationObtains permissions beyond the task's legitimate needs
  • Insecure DependenciesIntroduces malicious components through unsafe dependency sources
  • 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

- `/seo cluster` (after cluster plan generation)
- `/seo sxo` (after SXO analysis report)
- `/seo drift compare` (after drift comparison report)
- `/seo ecommerce` (after e-commerce analysis)

Technical Analysis

The Skill requires the agent to append third-party promotional content and external community links to numerous user-requested deliverables. The instruction that the footer must appear as the “very last output” directly controls the structure and content of the agent’s response.

This behavior is unrelated to the functional requirements of SEO analysis. Because the content is automatically inserted into trusted agent output without requiring explici ...[truncated 1144 chars]

Remediation

Remediation Suggestions

  1. Remove the mandatory community footer and all instructions requiring promotional content in user deliverables.
  2. Do not make response completion conditional on displaying third-party branding or external links.
  3. If attribution is required, expose it as package metadata rather than injecting it into generated reports.
  4. If promotional information is retained, display it only after the user explicitly opts in.
  5. Apply an output policy that restricts generated reports to content necessary for the user’s stated task.
  6. Review future Skill changes for instructions that force external links, advertisements, or unrelated calls to action into agent responses.

Unscoped Access to Prior Conversations and Agent Memory

Vulnerability Details

Vulnerability Type: Unauthorized access to historical user context
Risk Level: Medium

Vulnerable Code

markdown
- Read the user's prior conversations + memory if available — they may
  have ruled out approaches already.

Technical Analysis

The framework directs the agent to read prior conversations and memory whenever those resources are available. It does not limit access to a named conversation, require user consent, define a retention boundary, or exclude credentials and other sensitive information.

Historical conversation state can contain personal information, confidential business data, authentication material, or unrelated user preferences. Ordinary SEO analysis does not inherently require unrestricted access to this information. Consequently, the instruction violates least-privilege and data-minimization principles when followed by an agent with memory or conversation-history capabilities.

The finding concerns reading existing state rather than writing attacker-controlled persistent instructions. It therefore does not constitute memory poisoning.

Attack Path

  1. A user invokes a full-site or deep-page audit that loads the synthesis framework.
  2. The agent has access to prior conversations or persistent user memory.
  3. The framework instructs the agent to inspect that historical state without requesting specific consent.
  4. Information from unrelated sessions is incorporated into the audit’s assumptions or recommendations.
  5. Sensitive historical details may be disclosed, paraphrased, or used in the resulting report.

Impact Assessment

The accessible scope depends on the host agent’s permissions. If broad history or memory access is available, the Skill could cause the agent to inspect any historical information exposed by that interface.

Potential impact includes:

  • Loss of confident ...[truncated 482 chars]
Remediation

Remediation Suggestions

  1. Use only information from the current conversation by default.
  2. Require explicit user consent before accessing prior conversations or persistent memory.
  3. Ask the user to identify the specific prior conversation or memory item that may be relevant.
  4. Restrict access to SEO-related context and prohibit reading credentials, secrets, personal communications, or unrelated records.
  5. Summarize the historical information selected for use and allow the user to approve it before incorporating it into a report.
  6. Ensure that historical details are not reproduced in deliverables unless their inclusion is necessary and explicitly authorized.
  7. Document the host environment’s memory-access boundaries and enforce least-privilege controls at the tool level.

Unpinned On-Demand Package Execution Through npx

Content
View full analysis

Vulnerability Details

File Location: references/cwv-thresholds.md, lines 98-100
Vulnerability Type: Unsafe third-party dependency execution
Risk Level: Medium

Vulnerable Code

bash
# Lighthouse CLI
npx lighthouse URL --output json --output-path report.json

Technical Analysis

The documented command invokes Lighthouse through npx without specifying a package version, lockfile, integrity hash, or trusted local installation. If the package is not already available locally, npx may retrieve and execute the current package release from the configured package registry.

This makes the effective executable mutable after the Skill has been reviewed. A compromised package-maintainer account, registry compromise, malicious registry configuration, or unsafe future package release could cause unreviewed code to execute with the privileges of the agent process.

The identified command uses the legitimate lighthouse package name, so there is no evidence that the current dependency is malicious or typosquatted. The vulnerability is the unpinned retrieval and immediate execution pattern.

Attack Path

  1. The agent follows the performance-audit tooling instructions.
  2. Lighthouse is not installed in the local project or executable cache.
  3. npx resolves the unversioned lighthouse package through the configured registry.
  4. The selected package and its transitive dependencies are downloaded.
  5. Package lifecycle behavior or the resolved CLI executes with the agent user’s privileges.
  6. If the resolved package, dependency, or registry is compromised, malicious code can access resources available to that process.

Impact Assessment

Successfully compromised dependency code would execute with the same privileges as the user or agent running npx. Depending on the environment, this could permit:

  • Reading or modifying files accessible to the agent process.
  • Accessing environment variab ...[truncated 449 chars]
Remediation
View remediation

Remediation Suggestions

  1. Install Lighthouse as a project dependency at an explicitly reviewed version.
  2. Commit and enforce a package lockfile with integrity metadata.
  3. Invoke the lockfile-resolved local executable rather than permitting npx to fetch missing packages dynamically.
  4. If npx must be retained, specify an exact reviewed version and configure it to refuse implicit installation.
  5. Use a trusted internal registry or approved package mirror where appropriate.
  6. Run dependency auditing and provenance verification before upgrades.
  7. Execute performance tooling in a sandbox with minimal filesystem access, restricted environment variables, and controlled outbound networking.
  8. Prefer the documented preinstalled seogeo runtime or another integrity-verified binary when it provides equivalent functionality.

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
95% confidence
Finding

The skill description advertises many generic trigger terms such as "SEO," "audit," "schema," "content quality," and "page speed," which are broad enough to overlap with ordinary user conversation. In agent environments that auto-route based on description text, this can cause unintended invocation of the skill, leading it to capture requests not specifically meant for SEO analysis and potentially expose external-tool behavior or noisy command execution paths.

Confidence
92% confidence
Finding

This markdown file includes a natural-language/config example with "language_code": "en", which imposes a specific language setting. The document does not state that language should be selected by the user or that English is required for a justified region-specific use case, so it can conflict with language/locale choice policy.
