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.
Go's bcrypt package caps input at 72 bytes and returns ErrPasswordTooLong instead of silently truncating — one of several Go-specific quirks that trip up password hashing code.
Java's URLEncoder turns spaces into + instead of %20 — a form-encoding quirk that, mixed with double-decoding, still causes path-traversal bugs like CVE-2025-41242 in 2025.
OWASP requires session IDs carry at least 64 bits of entropy, yet a 2007 Rails flaw shows one dropped attribute is enough to make fixation trivial.

Stripe gives you a 5-minute replay window and GitHub a raw-body HMAC — but most outages trace back to one bug: verifying JSON after it's been re-serialized.
