Security audit

Open Data Integrator

Security checks for vulnerabilities and agentic risk

Overview

The skill is a coherent construction data-analysis helper, but users should treat its bundled connector code as demo/sample data rather than verified live open-data integration.

Install only if you are comfortable giving the skill filesystem access to user-supplied project files and potential network access for open-data lookups. Treat the included Python as illustrative/demo code unless you replace or verify the connectors against real data sources, and avoid relying on its sample price, labor, permit, or weather values for business decisions without independent validation.

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

Description-Behavior Mismatch

Medium
Category
Not specified by scanner
Confidence
95% confidence
Finding

The skill advertises integration of multiple open external datasets, but most connectors return hard-coded or simulated values. This is a software integrity issue: consumers may believe outputs are current external data when they are actually static placeholders, leading to incorrect analysis, reporting, or business decisions.

Missing User Warnings

Confidence
91% confidence
Finding

The markdown describes integrating data from sources including weather services, and the examples show supplying latitude, longitude, and project date ranges for enrichment and risk assessment. There is no visible warning that using the skill may disclose project-related location and timeline data to third-party services, which is a privacy-relevant behavior for markdown files.

Intent-Code Divergence

Medium
Category
Not specified by scanner
Confidence
96% confidence
Finding

The weather connector is presented as API-backed, but the implementation fabricates records instead of retrieving real source data. This can mislead downstream users into making planning or risk decisions based on false environmental inputs, undermining integrity and trust in the skill’s outputs.

External Transmission

Medium
Category
Data Exfiltration
Confidence
50% confidence
Finding

Data is being sent to an external URL. This could be legitimate telemetry or data exfiltration. Manual review is recommended.

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
91% confidence
Finding

The manifest description is generic and does not define clear activation boundaries, increasing the chance the skill is invoked in situations beyond its intended scope. For a skill with both filesystem and network permissions, ambiguous triggering raises the risk of unnecessary access to local data and external transmission during unrelated tasks.

Missing User Warnings

Medium
Category
Not specified by scanner
Confidence
95% confidence
Finding

The skill requests both filesystem and network permissions without any visible disclosure of what local data may be read or what information may be sent externally. This combination is especially risky because it enables a path for collecting local files and transmitting their contents to remote services under a broadly described data-integration purpose.

Natural-Language Policy Violations

Low
Category
Not specified by scanner
Confidence
84% confidence
Finding

The book reference presents a Russian title alongside English content, but the skill does not explain any language or locale expectation for users. Because the policy requires avoiding forced language/locale constraints without opt-in or justification, this mixed-language reference should be clarified.
