Security audit

memegen-rs

Security checks across malware telemetry and agentic risk

Overview

This is a simple meme-link skill that builds memegen.rs URLs, with no executable code, persistence, credentials, or hidden local access.

Install only if you are comfortable sending meme captions and any supplied background image URL to memegen.rs as part of a shareable URL. Do not use it with confidential text, private image links, or internal URLs.

Vague Triggers

Medium
Confidence
91% confidence
Finding
The invocation description is broad enough to match common user requests like making or captioning images, which can cause the skill to trigger in situations where the user did not clearly consent to using an external meme-generation service. Because this skill sends user-provided caption text and potentially remote image URLs to a third party, over-triggering increases the chance of unintended data disclosure and unnecessary external calls.

Missing User Warnings

Medium
Confidence
97% confidence
Finding
The skill description does not warn that caption text and any supplied background image URL are transmitted to memegen.rs, an external service. Users may unknowingly send sensitive text, internal URLs, or private image locations off-platform, creating a privacy and data-handling risk even though the skill itself only constructs a URL.
