SQL Injection vulnerability: Using string formatting (%s % table.name) is unsafe. Use parameterized queries instead:
cursor.execute("SELECT * FROM %s", [table.name])| # Since we can't parameterize the entire query, we'll validate it's a SELECT query | ||
| # This is a basic protection - in a real-world scenario, more robust validation would be needed | ||
| query = query.strip() | ||
| if not query.lower().startswith('select'): |

Security concern: The execute_query function accepts raw SQL queries with only basic validation. Consider using a proper SQL parser or query builder to prevent SQL injection attacks. The current startswith('select') check can be bypassed with comments or complex queries.

Error handling improvement needed: The generic Exception catch is too broad. Consider catching specific exceptions (sqlite3.Error, etc.) and providing more detailed error messages. Also, consider logging the errors for debugging purposes.

Performance concern: Both get_table_data and execute_query fetch all rows at once without pagination. This could lead to memory issues with large tables. Consider implementing pagination or limiting the number of rows returned.

Avoid string interpolation for table names; it may lead to SQL injection. Use Django's connection.ops.quote_name(table.name) to safely quote the identifier. - Reason this comment was not posted:
Marked as duplicate.
2. python/composio/tools/local/sqltool/actions/sql_query.py:58
- Draft comment:
The comment 'Use parameterized query to prevent SQL injection' is misleading since no parameters are used. The SELECT check helps, but consider clarifying or enhancing query validation. - Reason this comment was not posted:

Directly injecting table.name into the SQL query can lead to SQL injection if the table name is manipulated. Use parameterized queries or safely quote the identifier.
| cursor.execute("SELECT * FROM %s" % table.name) | |
| cursor.execute("SELECT * FROM %s" % connection.ops.quote_name(table.name)) |

There was a problem hiding this comment.
The comment about using a parameterized query is misleading; the query is executed as a raw string after a basic SELECT check, which may not fully prevent SQL injection. Consider using a proper parameterization scheme or more robust query validation.

| # Basic SELECT check to prevent non-SELECT queries |
