sql-sanitizer

library1.0.0jsnpmunverified

An Express.js middleware that detects and blocks SQL injection attacks by inspecting query strings, route parameters, and request bodies for common SQL injection patterns. Version 1.0.0 is the initial release with no further updates, limited to basic blacklist-based detection, and provides no configuration options, making it unsuitable for production without additional validation. Compared to more robust alternatives like knex or parameterized queries, this package offers minimal protection and is considered a last-resort or learning tool.

Code

Verified usage

Verified import paths — ran on the pinned version, not inferred.

default

✓ import sqlSanitizer from 'sql-sanitizer'

✗ const sqlSanitizer = require('sql-sanitizer')

Package is ESM-only since v1? README uses require, but modern Node may need import.

sqlSanitizer as middleware

✓ app.use(sqlSanitizer)

✗ app.use(sqlSanitizer())

Middleware is exported as a function, not a factory; calling it throws error.

require('sql-sanitizer')

✓ const sqlSanitizer = require('sql-sanitizer'); app.use(sqlSanitizer)

✗ const { sqlSanitizer } = require('sql-sanitizer')

Only one export; destructuring will yield undefined.

Shows basic usage of sql-sanitizer middleware in Express to block SQL injection patterns before handling requests.

import express from 'express'; import sqlSanitizer from 'sql-sanitizer'; const app = express(); app.use(sqlSanitizer); app.post('/login', (req, res) => { const { username, password } = req.body; // DANGER: This code is vulnerable; sql-sanitizer only blocks simple injection patterns // Use parameterized queries instead res.send('Login attempt'); }); app.listen(3000, () => console.log('Server running'));

Debug

Known issues

gotchaMiddleware only checks for blacklisted patterns; sophisticated injections can bypass it.

fix

Use parameterized queries (e.g., with knex or prepared statements) instead of relying on this middleware for security.

affects: >=1.0.0

gotchaPackage has not received updates since initial release; may have undiscovered vulnerabilities.

fix

Audit the source code manually or consider alternatives like 'sql-injection' or 'mariadb' with proper escaping.

affects: >=1.0.0

deprecatedThe README demonstrates CommonJS require, but the package might be ESM-only; try importing with 'import'.

fix

Use 'import sqlSanitizer from 'sql-sanitizer'' in modern Node.js.

affects: >=1.0.0

Errors

Common errors & fixes

TypeError: sqlSanitizer is not a function

Importing as a named export instead of default

fix

Use: import sqlSanitizer from 'sql-sanitizer'; or const sqlSanitizer = require('sql-sanitizer');

Cannot find module 'sql-sanitizer'

Package not installed or typo in package name

fix

Run: npm install sql-sanitizer

Middleware not blocking SQL injection

The blacklist may not cover the injection pattern used; or body parsing middleware not added

fix

Ensure express.json() is used before sqlSanitizer: app.use(express.json()); also consider using parameterized queries as a stronger defense.
