Security audit

Langflow

Security checks for vulnerabilities and agentic risk

Overview

This is a simple Langflow reference skill with broad trigger wording but no code, install steps, credential use, persistence, or hidden actions.

Before installing, consider whether Chinese-language trigger phrases and broad workflow terms fit your environment; the reviewed artifact itself is informational and does not ask to run code or access sensitive data.

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
  • Trigger AbuseOverly Broad Trigger, Shadow Command Trigger, Keyword Baiting Trigger
  • 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

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
95% confidence
Finding

The trigger phrases are generic terms like "langflow," "可视化工作流," and "流程构建," which can plausibly appear in ordinary user conversations that are not actually requests to invoke this skill. This can cause unintended skill activation, leading the agent to route user requests into the wrong capability, produce irrelevant responses, or expose skill-specific behavior without clear user intent.

Natural-Language Policy Violations

Low
Category
Not specified by scanner
Confidence
80% confidence
Finding

The file presents core descriptive content in both English and Chinese and later defines trigger phrases only in Chinese, but it does not state whether the skill supports multiple languages or let the user opt into a preferred language. This can create an implicit language/locale bias in how the skill is discovered or described.
