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.
eval(), exec(), and pickle.load() can each hand an attacker a Python interpreter — CVE-2020-1747 shows how one unsafe deserialization call became a real RCE.
os.system() and subprocess.run(shell=True) both hand a string straight to /bin/sh — one unescaped semicolon is enough to run arbitrary commands.
CVE-2013-0156 let attackers RCE Rails by feeding YAML into a parameter parser — the same insecure-deserialization pattern CTF players train on every weekend.
FastAPI shipped a built-in DI container in its very first release in December 2018 — but the same swappability that makes DI testable can quietly ship a mock into production.
DOM clobbering lets attackers hijack JavaScript logic using pure HTML — no <script> tag required — and it just bypassed DOMPurify's own sanitizer in 2026.
Fastify's encapsulation model isolates plugin state by default — but one `fastify-plugin` wrapper or a stray `skip-override` symbol can silently punch a hole through every boundary you had.
Broken Object Level Authorization has held the #1 spot on the OWASP API Security Top 10 since 2019 — and Django's get_object_or_404() does nothing to stop it.
Go's exec.Command never invokes a shell — yet CWE-78 command injection keeps shipping in Go services. Here's exactly how, and how gosec's G204 rule catches it.
Two backdoors nine years apart — event-stream in 2018, XZ Utils in 2024 — show why code-only AppSec programs fail. Here's a four-layer framework built from scratch.
