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.
WebSockets skip the same-origin policy and don't carry your REST auth for free. Cross-site WebSocket hijacking is the flaw teams miss. Here's how to secure the handshake.
Rust's borrow checker guarantees memory safety in your code — and nothing about the crates you pull in. A cargo build runs arbitrary code at compile time, before any safe code executes.
A single bad regex can freeze your entire Node.js event loop on one malicious request. Here is how catastrophic backtracking works, how to spot vulnerable patterns, and how to fix them without rewriting everything.
PyYAML is the default YAML parser for Python — and its history of arbitrary-code-execution CVEs from unsafe loading makes yaml.load() one of the most dangerous calls in the language.
Server-side request forgery turns your own backend into an attacker's proxy, reaching internal services and cloud metadata endpoints you never meant to expose.
Protocol Buffers is the serialization format behind gRPC and much of modern service-to-service traffic — and because parsing untrusted binary is its whole job, its real CVEs are denial-of-service by design, with a critical prototype-pollution bug in the JavaScript runtime.
Server-Side Request Forgery ranks #10 in the OWASP Top 10 (2021). A deep dive into cloud metadata theft, real CVEs like ProxyLogon, and how to stop SSRF in 2026.
Static secrets in CI are the credential most likely to be stolen — as the CircleCI breach proved. OIDC federation issues short-lived, per-run credentials with nothing to leak. Here is how to make the switch.
node-fetch brought the browser fetch API to Node.js and became a near-universal HTTP client — and its two real CVEs, a redirect-based header leak and a size-limit bypass, are exactly the kind of subtle bug that ships to millions of apps.
