Security checks for vulnerabilities and agentic risk

Overview

This is a straightforward JAX helper skill whose file loading and saving behavior is disclosed and aligned with numerical computing workflows.

Install only if you want local JAX helper functions for numerical arrays. Be careful when calling save(data, path), because it writes to the path you provide and may replace an existing .npy file; avoid using it on sensitive or unclear file paths.

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
  • 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
  • Excessive AgencyUnrestricted Tool Access, Autonomous Decision Making, Scope Creep

Missing User Warnings

Finding

This markdown file describes save(data, path) as writing array data to a filesystem path, but it does not include any warning that using the function will create or overwrite a local file. Because markdown files should disclose behaviors that affect user data or system state, this omission is a safety-related documentation gap.

Missing User Warnings

Low
Category
Not specified by scanner
Confidence
85% confidence
Finding

The save function writes data to disk via np.save, which can overwrite or create files, but the code provides no confirmation prompt, warning message, or explanatory comment about this side effect. In a code file, file writes are safety-relevant operations when they occur without any user disclosure.
