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.
A user lands in a group with more privilege than intended, and the access control system trusts it. Here is how CWE-842 happens and how to catch it.
When steps must happen in order and the server does not check, attackers skip or reorder them. CWE-841 explains workflow bypass and how to enforce state.
The javascript scheme can be written in encoded forms that slip past a naive filter. CWE-84 explains the bypass and why canonicalizing first is the fix.
Checking only the maximum lets negative numbers through. CWE-839 turns a missing lower bound into memory corruption in C and C++. Here is the fix.
When you encode output one way and the receiver decodes another way, data turns into commands. CWE-838 explains encoding mismatches and how to prevent them.
Votes, refunds and seat locks that should happen once can be repeated. CWE-837 is a business logic flaw. Here is how to enforce once only rules server side.

A crafted packet or file can leave a loop with no way out. CWE-835 explains how infinite loops arise in network code and how to stop them.
A loop does not need to be infinite to take a service down. CWE-834 covers unbounded iteration driven by attacker input and how to cap it.
