Confirmed finding summary

No confirmed security findings

The completed audit recorded no confirmed security findings. This is not proof that the Skill has no side effects.

Installation context

Historical evidence

This report may not describe the currently installable artifact. Open the current Skill page for install guidance.

Open current Skill page

This report does not block or authorize the manifest or ZIP.

No prompt injection, malicious network behavior, or data-exfiltration intent was found. Most external-command and blocker findings are false positives from markdown formatting, JavaScript template literals, comments, or PDF field identifiers; the confirmed findings are expected local filesystem reads and writes used for PDF processing.

Capability review items (25)

Medium

reference.md:59

Node.js fs operations

const existingPdfBytes = fs.readFileSync('input.pdf');

The reference example reads local PDF files from disk. This is expected for PDF processing, but it is real filesystem access that could expose unintended files if paths are chosen poorly.

Medium

reference.md:76

Node.js fs operations

fs.writeFileSync('modified.pdf', pdfBytes);

The guide or reference example writes generated PDF, text, image, or JSON output to local paths. This is expected behavior, but it can overwrite files or create outputs in unintended locations.

Medium

reference.md:137

Node.js fs operations

fs.writeFileSync('created.pdf', pdfBytes);

The guide or reference example writes generated PDF, text, image, or JSON output to local paths. This is expected behavior, but it can overwrite files or create outputs in unintended locations.

Medium

reference.md:151

Node.js fs operations

const pdf1Bytes = fs.readFileSync('doc1.pdf');

The reference example reads local PDF files from disk. This is expected for PDF processing, but it is real filesystem access that could expose unintended files if paths are chosen poorly.

Medium

reference.md:152

Node.js fs operations

const pdf2Bytes = fs.readFileSync('doc2.pdf');

Medium

reference.md:59

Python file write/append

with open("batch_merged.pdf", "wb") as output:

The guide or reference example writes generated PDF, text, image, or JSON output to local paths. This is expected behavior, but it can overwrite files or create outputs in unintended locations.

Medium

reference.md:500

Python file write/append

with open(output_file, 'w', encoding='utf-8') as f:

The guide or reference example writes generated PDF, text, image, or JSON output to local paths. This is expected behavior, but it can overwrite files or create outputs in unintended locations.

scripts/extract_form_field_info.py:143

Python file write/append

with open(json_output_path, "w") as f:

The shipped script writes output JSON or PDF data to a command-line path. This is intended functionality, but it is real local file write capability and can overwrite existing files.

SKILL.md:42

Python file write/append

The guide or reference example writes generated PDF, text, image, or JSON output to local paths. This is expected behavior, but it can overwrite files or create outputs in unintended locations.

Low

reference.md:474

Python glob/pattern matching

pdf_files = glob.glob(os.path.join(input_dir, "*.pdf"))

The batch-processing example enumerates PDF files in a user-supplied directory with glob. This is legitimate for PDF batching, but it can access more local files than intended if scoped poorly.

Risk findings

Confirmed security concerns are separated from items that still need review.

No confirmed security findings were recorded for this completed audit.

Remediation

Suggested fixes recorded by this audit. Applying them is the maintainer’s responsibility.

FIX-001
Medium
Local file overwrite risk

Validate output paths before writing PDFs, JSON files, images, or text files, and require confirmation before overwriting existing files.
FIX-002
Low
Broad batch-processing scope

Limit batch processing to explicit user-selected directories and document which files will be read before processing begins.
FIX-003
Low
Command-line example safety

Keep command examples limited to explicit PDF utilities, quote paths with spaces, and avoid constructing shell commands from untrusted text.
