Security audit

Linear API引擎(免费版)

Security checks for vulnerabilities and agentic risk

Overview

This Linear integration is not malicious, but it can make authenticated project-management changes without clearly requiring previews or user confirmation.

Install only if you are comfortable giving the agent a Linear API key and letting it send issue, project, and workflow data to Linear. Use a narrowly scoped or dedicated key where possible, avoid broad natural-language bulk requests, and require the agent to show the exact GraphQL request and affected Linear objects before any create, update, label, assignment, status, or cycle change.

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
  • Data ExfiltrationExternal Transmission, Env Variable Harvesting, File System Enumeration
  • Trigger AbuseOverly Broad Trigger, Shadow Command Trigger, Keyword Baiting Trigger
  • Behavioral ASTexec() Call, eval() Call, Dynamic Import
  • Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
  • Privilege EscalationExcessive Permissions, Sudo/Root Execution, Credential Access

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
85% confidence
Finding

The description says the skill is suitable for '需要linear api相关能力的开发场景' and repeats that it applies to '相关开发场景', which is vague and lacks clear trigger boundaries. This broad natural-language scope could overlap with many ordinary development requests involving project work, without specifying concrete invocation phrases or exclusion conditions.

Missing User Warnings

Medium
Category

Confidence
93% confidence
Finding

The skill explicitly supports creating, updating, and bulk-operating on Linear issues, cycles, projects, and workflows, but it does not prominently require confirmation before making remote state changes. In an agent setting with exec access, this raises the risk of unintended or overbroad modifications to production project data through natural-language prompting.

External Transmission

Data Exfiltration
Confidence
96% confidence
Finding

The skill is explicitly classified as MD+EXEC and instructs the agent to execute curl commands against an external GraphQL endpoint using an API key. External transmission is expected for this integration, but it still creates real risk because prompts can induce outbound requests that expose project metadata or perform authenticated actions on a third-party service.

Finding

This example shows an authenticated mutation to create an issue on a remote service. In the context of an agent with exec capability, demonstrating direct state-changing commands without built-in approval steps increases the likelihood of accidental or prompt-induced modification of external project data.

Natural-Language Policy Violations

Low
Category
Not specified by scanner
Confidence
93% confidence
Finding

The display name, summaries, and almost all instructional content are in Chinese, but the document does not state that Chinese is optional or provide an alternative language path. This can amount to a language policy issue when a skill effectively forces one language without user opt-in or a documented regional justification.
