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.
CWE-236 is about parameters, fields or attributes your product does not define or support. Ignoring them badly has crashed routers and chat clients.
CWE-235 is what happens when the same parameter appears more times than expected and two components read it differently. Learn how that opens bypasses.
When a function gets fewer arguments than it expects, it can still pop that many off the stack. CWE-234 explains the risk and the compiler level fix.
CWE-233 covers code that breaks when a request has too few parameters, or parameters nobody defined. Here is how it shows up and how to test for it.
A value your code does not recognize can crash a client or push it into the wrong state. CWE-232 explained with a safe default-case pattern.
What does your code do when it gets more values than it expects? CWE-231 explained, with a repeated-parameter example and a fix.
A parameter name with no value, a blank header or a null field can crash code or leak errors. CWE-230 explained with a validation example.
Relative path traversal uses '..' to climb out of a restricted folder. What CWE-23 covers, real cases from MITRE including package tooling, and how to stop it.
Code that assumes the right number of parameters, all defined, ends up in unexpected states. CWE-229 explained and how to validate counts.
