🚨 Severity: MEDIUM (Security Enhancement)
πŸ’‘ Vulnerability: Potential for malformed or malicious identifiers to reach the database layer or cause unexpected behavior if not validated early.
🎯 Impact: Defense-in-depth against injection-style attacks and resource exhaustion. Ensures consistent ID formatting.
πŸ”§ Fix:

  • Added a strict regex pattern to the Entity base model.
  • Introduced proactive validation in GraphQL and Bedrock Agent handlers using the Entity model.
  • Sanitized error messages to avoid reflecting unvalidated user input.
    βœ… Verification: Verified with uv run pytest and manual test cases for invalid IDs (length, characters).
