Security audit

Web Scrape Plus

Security checks for vulnerabilities and agentic risk

Overview

The skill is a disclosed web-scraping guide, but it includes authenticated scraping, session cookies, proxies, and anti-detection guidance without enough boundaries or warnings.

Review carefully before installing. Use this only for sites you are authorized to scrape, avoid sharing or storing raw session cookies, prefer test accounts where possible, and be aware that proxy rotation or stealth scraping can violate site policies or legal expectations.

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
  • Memory PoisoningPersistent Context Injection, Context Window Stuffing, Memory Manipulation
  • Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
  • Privilege EscalationExcessive Permissions, Sudo/Root Execution, Credential Access
  • Supply ChainUnpinned Dependencies, External Script Fetching, Obfuscated Code

Finding

Skill manipulates agent memory, state, or stored context. Memory corruption can alter personality, override safety rules, or cause unpredictable behavior.

Missing User Warnings

Medium
Category
Not specified by scanner
Confidence
94% confidence
Finding

The skill explicitly supports login-gated sites, session cookies, and proxies, but its top-level description does not warn users that these capabilities can expose account/session data or implicate privacy and authorization concerns. In a scraping skill with anti-detection features, omission of that warning increases the chance that users will provide sensitive cookies or use the skill against sites in ways that mishandle credentials or violate access expectations.
