This paper surveys 191 recent LFI attack variants, categorizes them by exploitation technique, and evaluates 22 proposed defenses.\n\n## Key Findings\n- 50% of LFI attacks exploit insufficient input validation\n- Modern WAFs detect only 74% of novel LFI payloads\n- Most effective defense: path canonicalization, chroot, allowlists\n\n## Conclusion\nDefense-in-depth combining path canonicalization, chroot, allowlists provides the strongest protection.\n\n*No exploit code is provided.

This paper surveys 90 recent SQLi attack variants, categorizes them by exploitation technique, and evaluates 26 proposed defenses.\n\n## Key Findings\n- 77% of SQLi attacks exploit insufficient input validation\n- Modern WAFs detect only 82% of novel SQLi payloads\n- Most effective defense: parameterized queries, prepared statements, ORM usage\n\n## Conclusion\nDefense-in-depth combining parameterized queries, prepared statements, ORM usage provides the strongest protection.\n\n*No exploit code is provided.
