Entity Framework Core's FromSqlInterpolated, ExecuteSqlInterpolated, and ExecuteSqlInterpolatedAsync methods properly parameterize interpolated string values. Arguments to these methods should not be flagged as SQL injection sinks since EF Core handles parameterization automatically.

Fix
Adds Entity Framework Core's
FromSqlInterpolated,ExecuteSqlInterpolated, andExecuteSqlInterpolatedAsyncmethods as sanitizers for thecs/sql-injectionquery.Problem
EF Core's interpolated SQL methods (
FromSqlInterpolated, etc.) acceptFormattableStringparameters and automatically parameterize interpolated values. Despite using C# string interpolation syntax ($"SELECT * FROM Users WHERE Id = {id}"), these methods are NOT vulnerable to SQL injection because EF Core extracts interpolated values as SQL parameters. The query incorrectly flags these as injection vulnerabilities.Validation
This is documented EF Core behavior: https://learn.microsoft.com/en-us/ef/core/querying/sql-queries#passing-parameters. The
FormattableStringoverload ensures values are parameterized.
