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 pointer that was never set points somewhere unknown. CWE-824 turns that into crashes, leaks and sometimes code execution. Here is how to avoid it.
Pointer arithmetic with an attacker influenced offset reads or writes the wrong memory. Here is how CWE-823 shows up in file and packet parsers.
CWE-822 happens when a value from an untrusted source becomes a pointer and gets dereferenced. See where it appears and how to defend against it.
A lock in the wrong place is as bad as no lock. CWE-821 covers shared resources that are synchronized, but not correctly. Here is what to check.
CWE-820 is a shared resource used by concurrent code with no synchronization at all. Here is why it matters for security and how to catch it.
A user-supplied image URL can carry script. CWE-82 covers scripting inside IMG attributes such as src, and why output encoding and URL checks matter.
Custom 403 and 404 pages that echo the request are a classic XSS spot. CWE-81 explains why, and the simplest fix is to stop echoing input.
CWE-807 is the habit of letting a cookie, header or hidden field decide who gets in. Real admin bypasses show why, and server side state is the fix.
Copying with the source size instead of the destination size is a classic overflow. Here is the pattern behind CWE-806 and how to stop it.
