Security checks for vulnerabilities and agentic risk

Overview

The skill’s research purpose is coherent, but it asks the agent to install/update and run mutable external code from a full Git repository in the user’s home directory.

Install only if you trust Cue and the sensedeal/cue-skills repository as live code providers. Before running, consider pinning the repository to a known commit, reviewing the runner script, and confirming that reading ~/.cue/config.json and spending Cue credits are acceptable.

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

Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
89% confidence
Finding

The file’s user-facing instructions and description are consistently presented only in Chinese, and there is no opt-in, alternative language option, or justification that the skill is intentionally region-specific. Under the stated policy, forcing a specific language without user choice is a natural-language policy violation.

Context-Inappropriate Capability

Medium
Category

Confidence
94% confidence
Finding

The skill instructs the agent to clone or update an entire external Git repository into the local home directory before use. That materially expands trust and execution scope beyond the declared research purpose: a compromised upstream repo, malicious mirror, or unexpected post-clone contents could introduce arbitrary code or unsafe tooling into the agent environment.

Context-Inappropriate Capability

Medium
Category
Not specified by scanner
Confidence
97% confidence
Finding

The skill directs the agent to execute a local Python script obtained from an external repository, creating a direct path from untrusted remote content to local code execution. In an agent setting, this is especially dangerous because the script can access local files, credentials, network resources, and persistence locations while appearing to perform a benign research task.
