A methodology for testing SPAs for client-side vulnerabilities
DOM XSS, token storage, and API exposure don't show up in a server-side scan — here's a repeatable methodology for testing React, Vue, and Angular apps.
Deep dives, practical guides, and incident analyses from engineers who build Safeguard. No fluff, no vendor FUD — just what you need to ship secure software.

NIST benchmark data puts some SAST false-positive rates near 78%. Reachability analysis and contextual triage are how teams cut that noise without missing real risk.
A CVSS 10.0 pre-auth RCE in React Server Components, exploited within 48 hours of disclosure — how the deserialization flaw works and how to mitigate it.
73% of open-source developers now use AI coding tools. Dynamic testing built for nightly crawls can't keep pace with apps that reshape their attack surface daily.
XS-Leaks bypass the Same-Origin Policy without running a single line of attacker script — they read state through timing, frame counts, and error events instead.
Two Critical Wasmtime sandbox-escape CVEs landed on the same day in April 2026 — proof that a wasm sandbox is only as strong as the runtime enforcing it.
A 2024 academic scan of the Tranco Top 1000 domains found roughly 17% vulnerable to web cache poisoning — here's how the attack works and how to stop it at the edge.
VS Code extensions run as trusted Node.js code with full disk and network access and no permission model to fall back on. Here is how to build one that does not become the next supply chain incident.
Stripe gives you a 5-minute replay window and GitHub a raw-body HMAC — but most outages trace back to one bug: verifying JSON after it's been re-serialized.
