SQL Injection Explained

A malicious user inputs something like:

' OR '1'='1

This input alters the SQL query:

SELECT * FROM users WHERE username='' OR '1'='1';

Because '1'='1' is always true, the query returns all rows from the users table instead of a specific user.

This allows attackers to bypass login or extract entire databases without authorization.

Prevention Tips:
✅ Always use prepared statements or parameterized queries.
✅ Sanitize and validate all user inputs.
✅ Apply least privilege principles on database access.

Stay safe and protect your database from SQL Injection attacks!

SQL Injection Attack — one of the oldest bugs, still one of the most dangerous.

SQL injection happens when user input is treated as executable SQL instead of data. A single unsafe query can expose sensitive data, bypass authentication, or even destroy entire tables.

String interpolation inside raw SQL is a red flag. It allows attackers to inject malicious logic directly into your query. Sanitizing input helps, but it is not enough on its own.

The real fix is parameterized queries.
When parameters are used correctly, the database engine treats input strictly as data — not executable code. No matter...
