This plugin protects Bubble app owners, admins, and end users from hidden upload attacks that can lead to XSS, account hijacking, phishing, CDN abuse, app crashes, legal exposure, and “how did this file get into my system?” moments. Instead of guessing, you get a clear, deterministic security report with risk level, reasons, and a SHA-256 fingerprint — so your workflows can confidently allow, block uploads.
Most Bubble apps blindly trust uploaded files. File extensions lie. MIME types lie. And once a dangerous file is saved, it’s already too late.
Secure File Upload Scanner is a client-side security firewall for Bubble that inspects the actual binary content of uploaded files before they are trusted or stored. It detects renamed executables, MIME spoofing, polyglot files, malicious SVGs, risky PDFs, ZIP abuse patterns, filename injection attacks, and more — all directly in the browser, with no servers, no external services, and no performance hit.
It does not pretend to be an antivirus (no client-side tool can), but it dramatically reduces real-world upload risk using the strongest security checks possible inside the browser — the exact layer Bubble is missing.
