Full Analysis
- [REMOTE_CODE_EXECUTION]: The skill instructs the user to download and execute a script from
https://cli.inference.shusing thecurl | shpattern. This allows arbitrary code execution from an external source without verification of the script content before execution in the local environment. - [COMMAND_EXECUTION]: The skill relies on the
Bashtool to run local browser automation viaagent-browserand cloud-based automation via theinfshCLI. It also suggests installing global system dependencies vianpm install -g appium. - [DATA_EXFILTRATION]: The
agent-browsertool includes an--allow-file-accessflag which grants the browser permission to read files from the local filesystem (e.g.,file:///path/to/document.pdf). This creates a high risk of local data exposure if the agent is directed to sensitive files or navigates to untrusted websites that could exploit this access to read local data. - [PROMPT_INJECTION]: As a browser automation skill, it inherently processes untrusted data from external websites. The
snapshotoperations ingest webpage content (DOM elements and text) directly into the agent's context. This presents a surface for indirect prompt injection where malicious instructions embedded in a webpage could manipulate the agent's behavior. - Ingestion points:
agent-browser open,infsh ... open, and subsequentsnapshotoperations inSKILL.md. - Boundary markers: No specific boundary markers or instructions to ignore embedded commands within webpage content are provided.
- Capability inventory: The skill utilizes the
Bashtool, providing broad system access including file system interaction, network capabilities, and browser control. - Sanitization: There is no evidence of sanitization, filtering, or escaping of the extracted webpage content (text, attributes, or metadata) before it is processed by the agent.
Recommendations
- HIGH: Downloads and executes remote code from: https://cli.inference.sh - DO NOT USE without thorough review
- AI detected serious security threats
