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!
