Security audit

multi-image-to-text

Security checks for vulnerabilities and agentic risk

Overview

This skill is a straightforward image OCR helper that processes user-provided images and returns extracted text without hidden execution or persistence.

Before installing, note that this skill will inspect the contents of images you provide and may create a Markdown file if requested. Avoid uploading sensitive images unless you are comfortable having their text extracted in the current session.

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
  • Trigger AbuseOverly Broad Trigger, Shadow Command Trigger, Keyword Baiting Trigger
  • Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
  • Data ExfiltrationExternal Transmission, Env Variable Harvesting, File System Enumeration
  • 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
93% confidence
Finding

The skill description is broad enough to overlap with many generic image-processing or OCR requests, which can cause unintended activation. While this is not a direct code-execution issue, misrouting user requests to the wrong skill can lead to incorrect handling of user data or unexpected tool use.

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
95% confidence
Finding

The trigger section defines when the skill should activate but does not define clear boundaries for when it should not. This ambiguity increases the chance of accidental invocation on adjacent workflows, especially broad 'analyze these images' requests, which can degrade security predictability and cause unnecessary access to image contents.

Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
92% confidence
Finding

The title and the entire specification require output in Chinese, including fixed headings such as "图片文字提取结果". This imposes a specific language/locale on users without opt-in or any stated regional/business justification, which matches the language-policy violation criteria.
