Pdf To Structured

Security checks for vulnerabilities and agentic risk

Overview

This skill is a straightforward PDF data-extraction helper, with ordinary local file output and dependency-installation risks users should manage.

Before installing, use a virtual environment, consider pinning or reviewing dependency versions, and keep extracted spreadsheets or text files in approved secure locations. For confidential PDFs, prefer local Tesseract OCR and require explicit user approval before using any cloud OCR service.

Vulnerability Patterns

Insecure DependenciesIntroduces malicious components through unsafe dependency sources
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

Missing User Warnings

Medium

Category: Not specified by scanner
Confidence: 90% confidence
Finding: The skill repeatedly demonstrates writing extracted PDF contents to local Excel, CSV, JSON, and text files without any warning that construction PDFs may contain sensitive commercial, operational, or personal data. In batch mode, this can amplify exposure by creating many plaintext or spreadsheet artifacts that may be stored in insecure locations, synced automatically, or shared unintentionally.
Content: No source excerpt is available for this finding.

Description-Behavior Mismatch

Low

Category: Not specified by scanner
Confidence: 95% confidence
Finding: The manifest describes this skill as extracting structured data from PDFs and converting outputs to Excel/CSV/JSON using OCR and pdfplumber. The quick reference at L440 adds 'Merge PDFs | pypdf | writer.add_page(page)', which is a document manipulation capability unrelated to structured data extraction or format conversion.
