Security checks for vulnerabilities and agentic risk

Overview

This is a straightforward web-search skill that sends user-provided search requests to the disclosed SkillBoss API and optionally saves results when the user asks it to.

Before installing, confirm you trust SkillBoss/HeyBoss with your search queries and API key. Do not include secrets, credentials, private customer data, or confidential internal project names in searches, and only use --output when you intend the results to remain on disk.

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
  • Taint TrackingDirect Taint Flow, Variable-Mediated Taint Flow, Credential Exfiltration Chain
  • Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
  • Privilege EscalationExcessive Permissions, Sudo/Root Execution, Credential Access
  • Supply ChainUnpinned Dependencies, External Script Fetching, Obfuscated Code

Tainted flow: 'SKILLBOSS_API_KEY' from os.environ.get (line 23, credential/environment) → requests.post (network output)

Critical
Category
Data Flow
Confidence
90% confidence
Finding

Credentials or environment variables flow to a network sink. This is a high-confidence indicator of credential exfiltration.

Missing User Warnings

Confidence
96% confidence
Finding

The skill clearly instructs users to send arbitrary search queries, filters, and related parameters to SkillBoss API Hub, but it does not explicitly warn that this data leaves the local environment and is transmitted to a third-party service. This can lead users or downstream agents to unintentionally disclose sensitive prompts, internal project names, personal data, or confidential research topics during web searches.

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
96% confidence
Finding

User search queries and filters are transmitted to a third-party API, but the tool does not provide an explicit privacy or disclosure warning at runtime beyond implying use of SkillBoss in the help text. In agent or enterprise contexts, users may enter sensitive prompts, internal names, or investigative terms without realizing that data leaves the local environment.

Missing User Warnings

Low
Category
Not specified by scanner
Confidence
90% confidence
Finding

The skill promotes saving search results to local files but does not clearly warn that retrieved content may be written to disk and persist beyond the current session. This can create unintended local data retention, especially if results contain sensitive research topics, user queries, or links/content that should not be stored on shared or monitored systems.
