Sticker Generator

Security checks for vulnerabilities and agentic risk

Overview

This sticker-generation skill is purpose-aligned and user-directed, with privacy and supply-chain cautions users should understand before use.

Install only from the official CellCog source, avoid running setup commands with elevated privileges, and consider pinning or reviewing package versions. Do not upload sensitive personal photos, confidential team images, regulated data, or private brand assets unless you are comfortable sending them to CellCog for processing.

Vulnerability Patterns

Insecure DependenciesIntroduces malicious components through unsafe dependency sources
Skill Instruction HijackingAlters the agent's session goals or safety constraints when the skill loads
Agent Memory PoisoningWrites attacker-controlled rules into memory that affect later sessions
Remote Payload Retrieval and ExecutionFetches external code whose behavior can change after review
Embedded Malicious CodeShips malicious scripts inside the skill and executes them locally

Missing User Warnings

Medium

Category: Not specified by scanner
Confidence: 96% confidence
Finding: The skill explicitly encourages users to upload reference photos and detailed prompts to generate stickers, but it does not clearly warn that those inputs are transmitted to an external CellCog service. This is a real privacy and data-handling issue because users may unknowingly send personal images, likenesses, team photos, or sensitive brand assets off-platform without informed consent.

Rp1

Medium

Category: MCP Rug Pull
Confidence: 92% confidence
Finding: The skill instructs users to run npx skills add cellcog/skills --skill cellcog without pinning a specific package or version. This creates a supply-chain risk: users may fetch unexpected or compromised code if the package, tag, or dependency resolution changes, and the risk is heightened because the command executes code from an external registry.
