Fix sQL query built by string interpolation in Nuxt
A SQL string is assembled with a template literal or concatenation and passed to a database driver. Any value interpolated into it is executed as SQL, so a request parameter can read, modify, or destroy data the query was never meant to touch. Use the driver's parameter binding instead; every driver has it.
high likely Nuxt CWE-89 / OWASP A03:2021
The vulnerable pattern in Nuxt
This finding comes from the Nuxt fixture in the owlwarden test
suite, in GET /api/users.
A value taken from the request is interpolated into SQL, so the caller controls part of the statement. That is enough to read other users' rows, bypass a WHERE clause, or drop a table.
The corrected handler
Bind the value; keep the SQL text constant.
await db.query('SELECT * FROM users WHERE id = $1', [id])If you are not using Nuxt
Pass the values as query parameters instead of interpolating them. Every driver supports it, and the binding is not optional formatting - it is what stops the value being parsed as SQL.
