Nano Banana Pro

Security checks across malware telemetry and agentic risk

Overview

This skill does what it claims: it generates or edits images through Google Gemini, but users should avoid sending sensitive prompts or images.

Install only if you are comfortable sending image prompts and any selected input images to Google's Gemini service. Do not use screenshots, documents, credentials, private photos, regulated data, or other sensitive content as input images unless you accept that external processing.

Findings (2)

Lp3

Medium

Category: MCP Least Privilege
Confidence: 93% confidence
Finding: The skill instructs use of an environment variable (`GEMINI_API_KEY`) and command execution, but the manifest does not declare corresponding permissions or capabilities. This creates a transparency and least-privilege problem: users and platforms cannot accurately assess that the skill accesses sensitive environment data and invokes external tooling.

Missing User Warnings

Medium

Confidence: 98% confidence
Finding: The skill sends user prompts and optionally local input images to Google's external API, but the description does not warn about this data transfer. Users may unknowingly expose sensitive text or image content to a third party, creating privacy and compliance risk.
