Image Compression

• Outcome: Review
• Latest audit: May 28, 2026, 12:28 PM
• Version:
  1.0.0

Overview

The skill mainly compresses images, but its send helpers can immediately upload user-selected images to WeChat or Telegram and one helper runs an unreviewed hard-coded local script.

Use the compression-only script when you only want local resizing. Treat the WeChat and Telegram helpers as upload/send tools: verify the image path, recipient, and account before running them, and avoid the WeChat helper unless you have inspected and trust the hard-coded external WeChat script on your machine.

Vulnerability Patterns

• Data Exfiltration: External Transmission, Env Variable Harvesting, File System Enumeration
• Prompt Injection: Instruction Override, Hidden Instructions, Exfiltration Commands
• Privilege Escalation: Excessive Permissions, Sudo/Root Execution, Credential Access
• Supply Chain: Unpinned Dependencies, External Script Fetching, Obfuscated Code
• Excessive Agency: Unrestricted Tool Access, Autonomous Decision Making, Scope Creep

Missing User Warnings

Medium

• Confidence: 87% confidence
• Finding: The skill documentation includes examples for sending images to WeChat and Telegram but does not clearly warn users that files may be transmitted to external messaging services. This creates a privacy and data-handling risk because users may run the provided commands without appreciating that local images will leave the device and be shared with third-party platforms.

Missing User Warnings

Medium

• Confidence: 94% confidence
• Finding: The script transmits a user-supplied image to WeChat immediately after compression without any explicit confirmation, preview, or destination verification. In an agent/skill context, this increases the risk of unintended data exfiltration because a mistaken path, automation misuse, or prompt-triggered invocation could send sensitive files to a chat target without the user's awareness at send time.

Missing User Warnings

Medium

• Confidence: 88% confidence
• Finding: The script transmits a user-supplied image to Telegram via `openclaw message send` without any confirmation, disclosure, or logging that a network transfer to a third-party service will occur. This creates a privacy and data-handling risk because users may believe the script only performs local compression, while it actually exfiltrates image content to an external messaging platform.
