About usContributeSmuggling through frontend files
The threat
HTML smuggling hides file data inside frontend assets and rebuilds the file at the last mile in the browser.
How the test works
Choose a carrier. The page extracts embedded test data from HTML, JavaScript, CSS, or SVG and rebuilds a DOCM file locally.
Try it yourself
✓
Test pass condition
The carrier, extraction, or reconstructed file is blocked.
