Security checks for vulnerabilities and agentic risk

Overview

This WeRead skill is purpose-aligned and clearly discloses its API key, network, private reading-data access, and export behavior.

Install only if you are comfortable giving the skill a WeRead API key and allowing it to read your WeRead shelf, reading stats, highlights, and personal thoughts. Confirm each data fetch/export carefully, especially cross-book analysis or Markdown/HTML exports that may contain private notes.

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

Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
93% confidence
Finding

The script’s description, prompts, errors, and privacy notices are all presented only in Chinese, including consent-related messaging. Because this file is a general-purpose code tool rather than a clearly documented region-specific compliance utility, forcing a single language without user choice fits the locale-policy violation criteria.

Natural-Language Policy Violations

Low
Category

Confidence
82% confidence
Finding

Lines L741-L742 set the page language from DATA.lang, defaulting to und, but the file provides no natural-language indication that language or locale is user-selectable or constrained for a justified regional purpose. Because locale behavior is being imposed by input/config without any visible opt-in or explanation in this file, it may violate the requirement to avoid forced language settings without user choice.
