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-1096 is a Singleton that can be created twice when two threads race. Duplicates, partial objects and deadlocks follow. Here is the broken pattern and the fix.
CWE-1095 is a loop whose exit condition depends on a value that the loop body changes. It is easy to misread, which is where off by one and infinite loop bugs come from.
CWE-1094 is an index range scan that can cover a huge number of rows in a large table. Slow queries are the symptom, and attackers can trigger them on purpose.
CWE-1093 covers needlessly complex internal data structures. They are hard to understand, slow, and hide the bugs that matter for security.
CWE-1092 is one function reused across several architectural layers. It blurs boundaries and makes changes risky. MITRE classes it as a quality issue.
CWE-1091 is a method that uses an object but never calls its finalize or destructor method. Memory and handles stay held longer than needed, slowing and eventually starving a service.
CWE-1090 is a method that directly accesses a member of another class. It signals poor encapsulation and makes code harder to understand and change.
A Struts action mapping with validate set to false disables the Validator and custom checks. CWE-109 explained and fixed.
CWE-1089 is a big table carrying too many indexes. Every write has to update them all, so performance drops and write heavy paths become easy to overload.
