Security audit

Seedance 2

Security checks across malware telemetry and agentic risk

Overview

This skill is a straightforward PoYo Seedance API helper that sends user-provided generation payloads to PoYo, with no hidden persistence or unrelated behavior found.

Install only if you intend to send generation prompts, image URLs, and any callback URL you provide to PoYo. Prefer setting POYO_API_KEY as an environment variable rather than passing it on the command line, and avoid submitting private images, secrets, internal URLs, or sensitive personal content unless you are comfortable sharing them with that service.

MCP Least Privilege
Confidence
91% confidence
Finding
The skill explicitly instructs use of shell tooling (`curl`) via a helper script, but the skill does not declare corresponding permissions. This creates a trust and review gap: an agent may execute shell-based network actions without clear permission metadata, increasing the chance of unreviewed external requests or misuse of local execution capability.

Missing User Warnings

Medium
Confidence
96% confidence
Finding
The skill directs the agent to send prompts, and potentially image URLs or callback URLs, to a third-party API but does not clearly warn users about that data transfer. This is dangerous because users may provide sensitive prompts or private image references without informed consent, resulting in unintended disclosure to an external service.

Missing User Warnings

Low
Confidence
87% confidence
Finding
The reference explicitly instructs users to send prompts, image URLs, and an optional callback URL to a third-party API, but it provides no warning that this data leaves the local system and may be stored or processed externally. In a skill that may be used with sensitive prompts or private image URLs, this omission can lead to unintentional disclosure of user data and webhook endpoint information.
