📝 WalkthroughWalkthroughThe URL guard module and ten helper functions are now publicly accessible. ChangesNetwork guard sharing
Estimated code review effort: 2 (Simple) | ~10 minutes Merge Risk: 🟠 High · up to The PR exports and reuses SSRF URL filters, but several special-use IPv4 and IPv6 ranges are still treated as globally reachable, allowing affected URLs to pass address checks. Because this weakens a high-impact security control, merge should wait for exhaustive classification coverage and regression tests, with the public validator surface narrowed or clearly constrained.
