Security reports
No reports found for this package in our research (last checked 2026-10-29).
Risks to watch for
- Local file access: The tool may read files on your computer to gather content for slides, which could expose sensitive documents if you're not careful about what folder you run it in.
- AI prompt injection: Malicious text pasted into slide content or project descriptions could trick the AI into running unintended commands or changing its behavior.
- Export leaks: Generated PDFs or PowerPoint files might accidentally include hidden metadata, notes, or images you didn't intend to share.
- Browser data: Even though it's browser-first, your slide projects are stored locally—but if you later sync or upload them, check what gets included.
- Dependency risks: As open-source, it depends on other packages; outdated dependencies could have security bugs.
How to lower the risk
Least-privilege permissions
- Run it in a separate user account or isolated container if possible.
- Only give it access to folders containing slide project files, not your whole home directory.
Network isolation
- Use it offline or block internet access if you're working with very sensitive content.
- Check the repository's actual network calls before trusting it with confidential data.
Monitoring
- Review generated slides carefully before sharing or exporting.
- Check exported PDF/PPTX files for unexpected metadata or hidden content.
Red flags to watch for
- If slides contain text you didn't write or images that seem wrong, re-check your input.
- Slow performance or unexpected crashes could mean a dependency issue or attack attempt.
