Security audit

FlowUs CLI

Security checks for vulnerabilities and agentic risk

Overview

This skill is a disclosed FlowUs CLI guide with explicit safeguards for installation, authentication, credentials, and remote writes.

Install this only if you want an agent to access or change FlowUs content. Approve installer, login, upload, and write actions only when you recognize the FlowUs identity, target page or database, and intended content; use a secret channel for tokens and prefer manual installation if official integrity data is unavailable.

Vulnerability Patterns
  • 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
  • Unauthorized Access and Privilege EscalationObtains permissions beyond the task's legitimate needs
Vulnerability Patterns
  • Excessive AgencyUnrestricted Tool Access, Autonomous Decision Making, Scope Creep
  • Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
  • Data ExfiltrationExternal Transmission, Env Variable Harvesting, File System Enumeration
  • Privilege EscalationExcessive Permissions, Sudo/Root Execution, Credential Access
  • Supply ChainUnpinned Dependencies, External Script Fetching, Obfuscated Code

Autonomous Decision Making

Medium
Category
Excessive Agency
Confidence
80% confidence
Finding

Skill enables autonomous high-impact decisions without human-in-the-loop verification. Critical operations (destructive commands, financial transactions, data deletion) should require explicit user confirmation.

Use the FlowUs CLI (`flowus`) for FlowUs V2 API work: pages, blocks,
databases, search, Markdown content, and files.

The CLI source repository may be private. Do not ask the user to clone source
code before using the CLI. Install or update the released binary from the
official FlowUs CDN only after the user explicitly approves it.

This is CLI resolution behavior, not authorization to expose a credential. Do
not pass `--token` in agent commands, logs, or shared shells: it can leak via
process listings or shell history. Do not ask users to paste bearer tokens into
chat. Use preconfigured `FLOWUS_TOKEN`, saved credentials, or an approved secret
channel; redact any credential that appears in command output.
