Entering text into a form field or URL that the database executes as part of a query. This allows attackers to read other users' data, bypass authentication, or delete tables.
Why it matters
To this day, one of the most common causes of database breaches. Just one place where user input is inserted into a query via string concatenation is enough to create a vulnerability.
What's missing without it
Without parameterized queries, every search field is a potential entry point into the database. Filtering 'dangerous words' is insufficient — they can be bypassed through encoding.
When it is used
When writing any query that uses user-provided data, and when auditing older code.
How we use it
Classic sign of vulnerability: the URL `?id=5` returns one article, while `?id=5 OR 1=1` returns all articles.
