Highest confirmed finding severity

Medium

5 confirmed security findings require attention.

Installation context

Check the current Skill page

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

Open current Skill page

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

Most static alerts are scanner artifacts from Markdown fences, local conversion commands, temporary directory use, and official documentation links. One static finding is confirmed because the troubleshooting command opens an unauthenticated localhost UNO listener; semantic review also found broad process termination, unbounded archive extraction, unescaped XML insertion, and unpinned package installation.

Confirmed security concerns (5)

RISK-001 Medium
SKILL.md:157
Broad Process Termination Can Cause Data Loss
The troubleshooting command terminates every soffice.bin process, including unrelated sessions with unsaved presentations, without confirmation or process scoping.
The documented killall command explicitly targets every process with the matching name, so unrelated LibreOffice sessions can be terminated.
RISK-002 Medium
SKILL.md:108-110
Unbounded Template Archive Extraction
The template workflow extracts a supplied archive without checking entries, links, expanded size, or resource limits, enabling disk exhaustion or unsafe archive contents.
The template path is accepted directly and passed to unzip without validation or extraction limits.
RISK-003 Medium
SKILL.md:112-115
Unescaped XML Template Injection
Placeholder values are inserted directly into content.xml, allowing supplied text to break XML structure or inject unintended ODF markup.
The example performs direct string replacement with str(value) and does not use XML parsing or escaping.
RISK-004 Medium
SKILL.md:139-140
Unpinned Python Package Installation
The installation examples fetch latest package versions without pins or hashes, increasing dependency drift and package supply-chain exposure.
Both pip commands omit versions and integrity hashes, so installation results can change without review.
RISK-005 Low
SKILL.md:158
Network reconnaissance
soffice --headless --accept="socket,host=localhost,port=8100;urp;"
The command starts a UNO socket listener on localhost without authentication. Any local process able to reach port 8100 could attempt to control the LibreOffice automation session.

Remediation

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

  1. FIX-001
    Medium
    The troubleshooting workflow terminates every soffice.bin process.
    Track the automation process ID and stop only that process after confirming no unsaved presentation work will be lost.
  2. FIX-002
    Medium
    Template archives are extracted without entry validation or resource limits.
    Validate archive paths and expanded size, reject links, cap resource use, and fail when extraction returns an error.
  3. FIX-003
    Medium
    Template values are inserted into content.xml without XML escaping.
    Use a structured XML library and insert values as escaped text nodes before rebuilding the ODP archive.
  4. FIX-004
    Medium
    Python package installation examples do not pin versions or verify artifacts.
    Pin reviewed versions, use a trusted package index, and verify hashes in reproducible environments.
  5. FIX-005
    Low
    The UNO listener accepts local socket connections without authentication.
    Use an isolated LibreOffice profile, start the listener only when required, and stop it immediately after automation.
