4.1🔒The Forgotten Attack Vector: AI OutputLLM output is often trusted and used in downstream operations without validation. When the model's output is interpolated into SQL queries…
4.2🔒Hands-On Lab: Testing Insecure Output Handling
4.3🔒Output Sanitization FrameworkCommon Mistake: Developers often sanitize user input diligently but pass LLM output directly to downstream systems without any validation…
4.4🔒Model Denial of Service (LLM04)Crafted inputs can consume excessive resources -- large context windows, recursive reasoning loops, or token-intensive outputs. In AI…
4.5🔒Defense Checklist- [ ] All LLM output rendered in HTML is escaped - [ ] All LLM output used in SQL uses parameterized queries - [ ] All LLM output used in…
