Input String Trimming and Length Bounding
AI forms accept arbitrarily long strings without max-length limits, causing database column truncation or layout breaks.
1-Click Fix Prompt for Cursor & Claude Code
Review my codebase for "Input String Trimming and Length Bounding" (INJ-010). Issue: AI forms accept arbitrarily long strings without max-length limits, causing database column truncation or layout breaks. Remediation required: Apply max length constraints (e.g. z.string().max(255)) on all text inputs in your schemas. Please: 1. Locate any occurrences of this issue across my repository. 2. Refactor the code to follow production standards without breaking existing functionality. 3. Provide a clear command or step to test and verify the fix.
Why AI Assistants Write This Bug
AI forms accept arbitrarily long strings without max-length limits, causing database column truncation or layout breaks.
AI code generation prioritizes immediate syntax execution over production edge cases. When an assistant hits an undefined variable or strict type error, it frequently takes the path of least resistance rather than implementing standard pre-launch security patterns.
