SQL and data-query injection
This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.
Check exposure
- Trace request, message, file, and stored values into SQL, ORM query fragments, filters, sort expressions, and other data-query languages.
- Inventory database roles, reachable schemas, multi-tenant boundaries, and whether stacked or administrative operations are enabled.
- Check both direct queries and second-order use of previously stored values.
Remediate safely
- Use parameterized queries or safe query builders for all values; map identifiers and operators through explicit allowlists.
- Remove raw query concatenation and give the application account only the tables and operations it requires.
- Update affected data-access components and add regression tests for query structure preservation with inert edge-case inputs.
