Vision Understanding

Security checks for vulnerabilities and agentic risk

Overview

This skill is a straightforward guide for turning media into text with external multimodal models, with no hidden code, persistence, or privilege escalation found.

Before installing, treat this as a media-processing skill that may send images, documents, audio, or video to external model providers. Avoid using it on highly sensitive IDs, medical records, financial documents, private recordings, or confidential screenshots unless that disclosure is acceptable.

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
  • Trigger AbuseOverly Broad Trigger, Shadow Command Trigger, Keyword Baiting Trigger
  • Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
  • Privilege EscalationExcessive Permissions, Sudo/Root Execution, Credential Access
  • Supply ChainUnpinned Dependencies, External Script Fetching, Obfuscated Code

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
95% confidence
Finding

The trigger phrase "Any media in, text out task" is so broad that it can cause the skill to be invoked for many unrelated or sensitive workflows, including documents, screenshots, receipts, IDs, and private audio/video. Over-broad routing increases the chance of accidental exfiltration of sensitive user content to external multimodal providers without clear user awareness or narrower task gating.

Missing User Warnings

Medium
Category
Not specified by scanner
Confidence
95% confidence
Finding

The skill instructs collection of media as a URL or base64 but does not warn that this content may be transmitted to external model providers, which can include highly sensitive images, documents, audio, or video. Users or calling agents may unknowingly pass private data such as receipts, screenshots, IDs, or conversations to third-party endpoints, creating confidentiality and compliance risk.
