Project Management

Security checks for vulnerabilities and agentic risk

Overview

This is a documentation-only CellCog project-management skill whose sensitive actions are disclosed and aligned with document workspace use, with some install and sharing precautions users should understand.

Before installing, verify you are using the official CellCog package or skill source and consider installing in an isolated environment. Treat generated signed URLs like temporary secrets: share them only with trusted recipients, use the shortest practical expiration, and avoid using them for highly confidential documents unless that sharing is intended.

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 prominently encourages generation and sharing of signed document URLs, including cross-agent, human, and external tool usage, but does not provide a strong warning that these URLs bypass normal CellCog authentication and expose raw document contents for the full validity period. In a project-management/document-workspace context, this materially increases the chance of unintentional data leakage, especially for sensitive files, because readers may treat signed URLs as routine convenience links rather than secret bearer tokens.

Rp1

Medium

Category: MCP Rug Pull
Confidence: 92% confidence
Finding: The skill instructs users to install a package via npx skills add cellcog/skills --skill cellcog without pinning a specific version or immutable source. That creates a supply-chain risk: users may fetch whatever package version is current at install time, including a compromised or malicious update, and the installation path is especially sensitive because it executes code during setup.
