SQL Injection Explained




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!
