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

Check the current Skill page

This page summarizes report evidence only. The Skill page provides the canonical install advisory.

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

The review confirmed four unsafe ZIP extraction calls that can permit Zip Slip when processing a crafted Office archive. The remaining static matches are false positives from OOXML namespaces, templates, documentation, or local document-processing operations; no prompt injection, credential theft, or network exfiltration was found. Static review was capped at 400/460 representative findings; omitted static matches are unconfirmed, so automatic publishing stays disabled until manual review.

Capability review items (4)
High
ooxml/scripts/unpack.py:17
Archive extract all (zip slip risk)
zipfile.ZipFile(input_file).extractall(output_path)
The code calls ZipFile.extractall on a supplied Office archive without validating member paths. A crafted archive can write files outside the intended extraction directory.
High
ooxml/scripts/validation/base.py:891
Archive extract all (zip slip risk)
zip_ref.extractall(temp_path)
The code calls ZipFile.extractall on a supplied Office archive without validating member paths. A crafted archive can write files outside the intended extraction directory.
High
ooxml/scripts/validation/docx.py:201
Archive extract all (zip slip risk)
zip_ref.extractall(temp_dir)
The code calls ZipFile.extractall on a supplied Office archive without validating member paths. A crafted archive can write files outside the intended extraction directory.
High
ooxml/scripts/validation/redlining.py:70
Archive extract all (zip slip risk)
zip_ref.extractall(temp_path)
The code calls ZipFile.extractall on a supplied Office archive without validating member paths. A crafted archive can write files outside the intended extraction directory.

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.

  1. FIX-001
    High
    Unsafe archive extraction of Office files
    Validate every ZIP member path resolves beneath the chosen extraction directory before writing it. Reject absolute paths, parent traversal, symlinks, and oversized archives.
  2. FIX-002
    Medium
    Static review capped
    Manually review the omitted 60 static analyzer matches or reduce bundled generated/vendor/reference content before enabling automatic publication.
  3. FIX-003
    Medium
    External converters process document input
    Run Pandoc, LibreOffice, and related converters with timeouts in a restricted temporary workspace when processing untrusted documents.
  4. FIX-004
    Low
    Dependency setup uses privileged examples
    Document non-privileged installation options and require explicit user confirmation before any package installation command.
