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.
Server-Side Template Injection turns template engines into code execution engines. This guide covers SSTI in Jinja2, Twig, Freemarker, and other engines, with detection techniques and layered defenses.
Svelte's compile-time approach reduces runtime attack surface, but SvelteKit introduces server-side considerations that require deliberate security attention. A practical guide.
Authentication bypass vulnerabilities let attackers access protected resources without valid credentials. This guide covers the most common bypass patterns found in modern web applications and how to prevent each one.
SRI protects against CDN compromises and supply chain attacks on client-side scripts. Most web applications do not use it. Here is what they are missing.
Chrome's Manifest V3 restricts extension capabilities in the name of security. The changes help, but they do not solve the browser extension supply chain problem.
Service workers give Progressive Web Apps powerful offline and caching capabilities, but they also create a persistent attack surface that outlives the browser tab. Understanding this surface is critical.
CDN cache poisoning turns your performance infrastructure into an attack vector. When the cache serves malicious content to every user, the blast radius is massive and immediate.
Session management vulnerabilities enable account takeover, privilege escalation, and data theft. This guide covers session ID generation, storage, lifecycle, and the attacks that exploit weak session handling.
Content Security Policy is the strongest browser-side defense against XSS. But most CSP deployments are bypassable. Here is why, and how to fix it.
