Security checks for vulnerabilities and agentic risk

Overview

This skill is a straightforward presentation-generation wrapper for a third-party API, with the main risk being that user-provided content is sent to SkillBoss/HeyBossAI.

Install only if you are comfortable sending prompts, drafts, pitch decks, reports, and related instructions to SkillBoss/HeyBossAI using your SKILLBOSS_API_KEY. Avoid submitting secrets, regulated data, or confidential business material unless that provider is approved for your use case.

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
  • MCP Least PrivilegeUnderdeclared Capability, Wildcard Permission, Missing Permission Declaration
  • Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
  • Privilege EscalationExcessive Permissions, Sudo/Root Execution, Credential Access
  • Supply ChainUnpinned Dependencies, External Script Fetching, Obfuscated Code
Findings (6)

Undeclared Tool Scope

Medium
Category
MCP Least Privilege
Confidence
95% confidence
Finding

The skill exposes shell-based execution examples and depends on a local script, but it does not declare any explicit tool scope or allowed-tools boundary. This weakens least-privilege controls and can let an agent invoke shell capabilities more broadly than the skill metadata suggests, increasing the chance of unintended command execution or misuse.

Missing User Warnings

Medium
Category
Not specified by scanner
Confidence
98% confidence
Finding

The skill encourages users to submit arbitrary presentation or document content to a third-party API, but it does not warn users that their content will leave the local environment. This creates a data leakage and consent problem, especially if users provide confidential business plans, reports, or proprietary text.

External Transmission

Medium
Category
Data Exfiltration
Confidence
92% confidence
Finding

The skill explicitly transmits user-supplied content to an external endpoint at api.heybossai.com for generation. In this skill's context, external transmission is expected functionality, but it is still security-relevant because sensitive prompts, documents, or business content may be exposed to a third party and subject to external retention or processing.

Finding

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

External Transmission

Medium
Category
Data Exfiltration
Confidence
90% confidence
Finding

This function performs an authenticated POST to a remote API and includes user-controlled content in the JSON request body. While external transmission is expected for this skill's purpose, it is still a genuine security/privacy concern because potentially sensitive input is exported to a third party without safeguards such as consent prompts, redaction options, or destination validation controls.

Missing User Warnings

Medium
Category
Not specified by scanner
Confidence
95% confidence
Finding

The script transmits user-supplied content to a third-party service using curl, but it does not provide an explicit user-facing notice at execution time that prompt/content data will leave the local environment. In a skill that may be used with sensitive business drafts, pitch decks, or internal documents, this creates a real privacy and data-handling risk if users assume processing is local.
