INJECT-004Medium severity-8 points

SQL built with % / .format() / + in execute() (Python)

Part of Security, which counts for 30% of the overall score. When this check fires it deducts 8 points from that category, once per scan, no matter how many places it turns up.

What it detects

A cursor execute() call builds its SQL string with %-formatting, .format(), or concatenation instead of passing parameters as the second argument.

Why it matters

Building the SQL inside execute() with %-formatting, .format(), or + puts the value into the query text instead of binding it, which is a SQL injection risk. The DB-API second argument exists exactly to avoid this. It is a heuristic because it cannot confirm the formatted value is user-controlled.

How to fix it

Move the values out of the string and into the execute() parameters: cursor.execute("... WHERE name = %s", (name,)). Never use %, .format(), or + to assemble a query. For an IN clause, generate the right number of placeholders and pass a tuple.
