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.
ASVS V1.3.3 requires sanitizing data headed for dangerous contexts: allow only safe characters and cap length. See an allowlist helper and how to test it.
ASVS V1.3.2 says avoid eval and expression engines like SpEL. See safe replacements in Python, JavaScript and Java, plus tests and review tips.
ASVS V1.3.12 requires regexes free of exponential backtracking and bounded input. Find risky patterns, use linear time engines and test with long inputs.
ASVS V1.3.11 requires sanitizing user input before it reaches mail systems. Learn to block header injection in contact forms and test your mailer.
ASVS V1.3.10 requires sanitizing format strings that may resolve in unexpected ways. See safe printf, str.format and logging patterns and a quick test.
ASVS V1.3.1 requires untrusted rich text HTML to pass through a well known sanitizer. See DOMPurify and Python patterns, tests, and the mistakes to avoid.
ASVS V1.2.9 requires escaping regex metacharacters in user input used inside patterns. See built in escape functions and a test that catches the gap.
ASVS V1.2.8 requires LaTeX processors without shell escape and a command allowlist. See the flags, a safe wrapper and the tests that prove it works.
ASVS V1.2.7 requires XPath queries to use parameterization or precompiled expressions. See a safe Java and Python pattern and how to test for injection.
