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.
CSRF makes a logged in user's browser send a request they never intended. Learn how it works, a Flask example, and the defenses MITRE lists.
CWE-351 happens when code cannot tell different kinds of elements apart, such as user clicks and scripted ones. Learn the pattern and the review habits that catch it.
CWE-350 is trusting a hostname from reverse DNS to grant access. Attackers who control the DNS for their IP can say anything. Here is the fix.
When a filter strips dot-dot-slash once, odd sequences like '.../...//' collapse into the very thing it removed. How CWE-35 works.
CWE-349 is a parser that trusts everything inside a trusted package, including the parts nobody vouched for. Signed data with extra content is the classic case.
CWE-348 is reading data from the weaker of two sources, like a client supplied IP header over the real connection address. Here is the pattern and the fix.
CWE-347 is signatures that are skipped or checked wrongly. Learn the common mistakes, a JWT example in Python, and how to verify properly.
CWE-346 is trusting data or messages without verifying where they came from. DNS cache poisoning, Mark-of-the-Web gaps and postMessage bugs share the root.
CWE-345 is accepting data without proving where it came from. Unsigned firmware and weak checksums show the damage, and signatures show the way out.
