Security checks for vulnerabilities and agentic risk

Overview

The skill is mostly API documentation for SkillBoss, but it combines a misnamed manifest with broad external model, email, SMS, document, and audio handling without clear safety scoping.

Review this skill before installing. It needs a SkillBoss API key and is designed to send user-provided content to HeyBoss/SkillBoss and downstream model or tool providers. Avoid using it with secrets, private documents, sensitive audio, or contact data unless you trust that service's data handling, and require explicit user confirmation before sending email or SMS messages.

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
  • Excessive AgencyUnrestricted Tool Access, Autonomous Decision Making, Scope Creep
  • Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
  • Privilege EscalationExcessive Permissions, Sudo/Root Execution, Credential Access
  • Supply ChainUnpinned Dependencies, External Script Fetching, Obfuscated Code

Missing User Warnings

Medium
Confidence
98% confidence
Finding
Across chat, speech, document, search, email, and other examples, the skill instructs sending prompts, audio, documents, URLs, and contact data to an external API without any privacy, consent, retention, or third-party processing warning. In an agent setting, this increases the risk of sensitive user data being exfiltrated to external providers under the guise of normal tool usage.

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

Scope Creep

Medium
Confidence
90% confidence
Finding
The documented example downloads externally returned content and writes it to a local file (`curl -o sunset.png`) even though the manifest only declares Bash and Read, creating a mismatch between declared capability and demonstrated behavior. This can mislead reviewers and agents about the skill's effective permissions and can result in unintended local file creation from untrusted remote data.

Save to file:

```bash
URL=$(curl -s -X POST https://api.heybossai.com/v1/run \
  -H "Authorization: Bearer $SKILLBOSS_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"model": "mm/img", "inputs": {"prompt": "A sunset over mountains"}}' \
Confidence
88% confidence
Finding
This workflow not only calls the external API but also downloads a remotely supplied URL and writes it locally, creating a side effect based on untrusted external response data. That increases risk beyond ordinary transmission because it can lead to unexpected file creation, storage of unsafe content, or misuse in environments that did not clearly authorize writes.
