Security Audit

Safe

v10 • 7/21/2026 Open versioned report

Most static matches are false positives caused by OOXML schemas, documentation, JavaScript template literals, and ordinary local presentation tooling. Four ZIP extraction calls are confirmed high-risk because they use extractall without validating archive member paths. No prompt injection, credential exfiltration, or malicious network intent was found in the reviewed context. Static review was capped at 400/506 representative findings; omitted static matches are unconfirmed, so automatic publishing stays disabled until manual review.

What You Can Build

Create Client Decks

Turn an outline into a polished PPTX deck with charts, images, and thumbnail checks.

Refresh Course Materials

Update lecture slides while preserving template layouts, fonts, and speaker notes.

Repurpose Internal Templates

Build a new presentation from approved template slides and replace placeholder content safely.

Try These Prompts

Create a Simple Deck

Create a five-slide PowerPoint about [topic]. Use a clear visual style, one main idea per slide, and generate thumbnails for review.

Update an Existing Deck

Open [presentation.pptx], summarize its structure, update the slides with [new content], validate the file, and show thumbnail results.

Reuse a Template

Use [template.pptx] to create a deck for [audience]. Inventory the template, choose suitable slide layouts, replace text, and check overflow.

Edit OOXML Directly

Unpack [presentation.pptx], edit the OOXML to change [specific element], validate against the original file, repack, and verify thumbnails.

Best Practices

Work from copies of original presentations and keep source files available for validation.
Generate thumbnails after each major edit to catch overflow, overlap, and contrast issues.
Sandbox untrusted PPTX and HTML files before unpacking archives or rendering pages.

Avoid

Do not skip validation after direct OOXML edits.
Do not use template slide indices before confirming the template inventory.
Do not render untrusted HTML with local file access in a privileged environment.
