Web Scraping

Security checks for vulnerabilities and agentic risk

Overview

This web-scraping skill is purpose-aligned and transparent about using browser automation, authenticated pages, and workspace files, with no hidden code or persistence.

Before installing, understand that this skill can guide an agent to scrape dynamic or login-gated pages and save larger results in the workspace. Use it only for sites and fields you intentionally specify, avoid scraping secrets or unnecessary personal data, and review saved files when working with authenticated content.

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
  • Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
  • Privilege EscalationExcessive Permissions, Sudo/Root Execution, Credential Access
  • Supply ChainUnpinned Dependencies, External Script Fetching, Obfuscated Code

Vague Triggers

Medium

Confidence
89% confidence
Finding

The skill description is broad enough to trigger on many generic requests involving websites, summaries, monitoring, or data collection, which can cause the agent to invoke browser automation or scraping behaviors in situations where a narrower skill should not. In this context, the risk is amplified because the skill explicitly includes login-gated flows and persistent data collection, increasing the chance of unnecessary access to authenticated content or over-collection of site data.

Missing User Warnings

Medium
Category
Not specified by scanner
Confidence
94% confidence
Finding

The skill advertises support for login-gated browsing and saving scraped results to workspace files without warning the user that authenticated content may be accessed and persisted. This creates a meaningful privacy and security risk because users may not realize the skill can operate within session-authenticated contexts and store potentially sensitive scraped data locally for later exposure or misuse.
