Security checks for vulnerabilities and agentic risk

Overview

This skill is a simple documented example for sending prompts to SkillBoss's external LLM API, with no local install, persistence, or hidden execution behavior.

Install only if you are comfortable sending prompts and any included text to SkillBoss's API. Use a scoped SkillBoss_API_KEY where possible and avoid submitting secrets, confidential business data, personal data, or regulated content unless your policy allows that third-party processing.

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
  • Data ExfiltrationExternal Transmission, Env Variable Harvesting, File System Enumeration
  • Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
  • Privilege EscalationExcessive Permissions, Sudo/Root Execution, Credential Access
  • Supply ChainUnpinned Dependencies, External Script Fetching, Obfuscated Code
  • Excessive AgencyUnrestricted Tool Access, Autonomous Decision Making, Scope Creep

Finding

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

Missing User Warnings

Medium
Category
Not specified by scanner
Confidence
95% confidence
Finding

The skill explicitly sends user prompts to a third-party API but does not warn users that their prompts and any included data will be transmitted off-platform. This creates a real data exposure risk because users may unknowingly submit sensitive or regulated information to an external service.

Content

No source excerpt is available for this finding.

External Transmission

Medium
Category
Data Exfiltration
Confidence
92% confidence
Finding

The request includes prompt content and an API bearer token in an outbound call to a remote service. Although the token is placed in an authorization header rather than exposed in output, the skill still establishes a trust boundary crossing where user content is transmitted externally.

Finding

This line contains the concrete remote endpoint used for API submission, confirming that prompt content is sent outside the local trust boundary to SkillBoss. In context, this is expected functionality, but it remains a real egress vector with privacy and compliance implications if users submit sensitive material.

Finding

The external URL in the curl example is part of an operational command that transmits message content to SkillBoss. Because the documentation lacks strong warnings, users may treat this as a harmless local example rather than a real external data transfer.
