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.
Logs are supposed to be your source of truth during an incident. Log injection lets attackers forge entries, break parsers, and — in the worst cases — trigger code execution from a log line.
JSON Web Tokens are only as safe as how you verify them. The alg:none trick, RS256-to-HS256 confusion, and weak secrets have all led to full auth bypass.
A contact form that builds emails from user input can be turned into a spam relay or a phishing generator through SMTP header injection. Here's how the attack works and how to neutralize it.
Mass assignment lets attackers set fields you never meant to expose — like isAdmin or accountBalance — by adding them to a request body. Here is the fix.
YAML looks like a harmless config format, but the wrong parser call turns a config file into a code-execution engine. Here's how YAML deserialization attacks work and how to parse safely.
Insecure deserialization turns a trusted data-loading routine into a remote code execution primitive. Learn how gadget chains work and how to deserialize untrusted data safely.
SSTI happens when user input is compiled as template code instead of rendered as data, often leading straight to remote code execution. Here is how to prevent it.
XXE abuses an XML parser's ability to load external entities to read local files, reach internal services, or knock a server offline. Here is how to stop it.
XSS lets an attacker run their JavaScript in your users' browsers — stealing sessions, rewriting pages, and pivoting to account takeover. This guide covers the three XSS types and the defenses that actually hold.
