Security Concern: SQL Injection Risk
The use of raw SQL queries (execute_sql) with template literals can potentially expose the application to SQL injection attacks if not properly sanitized or parameterized. Although this script is likely run in a controlled migration environment, it's a good practice to avoid forming SQL commands directly from input variables or using parameterized queries or stored procedures to mitigate such risks.
Recommendation:
Consider using parameterized queries or stored procedures to enhance security, especially if any part of the SQL command can be influenced by external input in future modifications.
| await supabaseAdmin.rpc('execute_sql', { | ||
| sql: ` | ||
| CREATE TABLE market_wir_transactions ( | ||
| id UUID PRIMARY KEY DEFAULT uuid_generate_v4(), | ||
| user_id UUID NOT NULL REFERENCES users(id) ON DELETE CASCADE, |

Potential SQL Injection and Dependency on uuid_generate_v4()
The SQL query for creating the table is embedded directly in the code and executed without explicit sanitization or parameterization, which could expose the system to SQL injection vulnerabilities. Additionally, the use of uuid_generate_v4() as a default value assumes that this function is available in the database, which might not be the case in all environments.
Recommendation:
- Use parameterized queries or stored procedures to avoid SQL injection.
- Ensure that
uuid_generate_v4()is available in your database setup or provide an alternative method for generating UUIDs.

Lack of Verification After Table Creation
The script logs a success message after executing the table creation command but does not verify whether the table and indexes were actually created. This could lead to situations where the script reports success, but the operation failed due to underlying SQL errors or permission issues.
Recommendation:
- Implement checks to verify the successful creation of the table and indexes. This could involve querying the database to confirm the existence of the table and indexes after the creation commands have been executed.

Potential Issue with UUID Generation
The SQL command for creating the users table assumes the availability of the uuid_generate_v4() function, which is provided by the uuid-ossp extension. This extension is created later in the script (lines 109-111). It's recommended to ensure that the extension is created before any table that requires it to prevent runtime errors during the table creation process.
Suggested Change:
Move the block of code that ensures the uuid-ossp extension exists to a point before any table creation that depends on it. This change would enhance the reliability of the database initialization process.

Enhancement for Session Table Management
The creation of the sessions table includes an index on the expired field, which is excellent for performance when querying or cleaning up expired sessions. However, there is no automated mechanism shown here for handling the cleanup of expired sessions. Over time, without proper cleanup, the sessions table could grow significantly and impact performance.
Suggested Enhancement:
Implement a routine or scheduled task that periodically removes expired sessions from the sessions table. This could be done within this script or as a separate maintenance script, ensuring that the sessions table remains manageable and does not negatively impact database performance.
