Security Architecture

VaultQR is engineered from the ground up to comply with strict OWASP standards, ensuring enterprise-grade safety for both users and infrastructure.

XSS & Buffer Overflow Prevention

All user inputs are rigorously validated using Zod schemas to prevent Buffer Overflow payloads. Before rendering, data is purged through DOMPurify to neutralize Cross-Site Scripting (XSS) vectors.

Strict Security Headers

Our server enforces an aggressive Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and anti-clickjacking headers to protect against man-in-the-middle and UI redressing attacks.

Malware-Free SVG Exports

Generated SVG files are strictly serialized as valid XML blobs. This prevents hackers from injecting hidden Javascript payloads directly into the downloadable QR Code files.
