If the application directly concatenates user input from the id= parameter into a database query without sanitization, it faces high susceptibility to SQL Injection (CWE-89).
: Tells Google to look for the following string within the URL of a website.
: An attacker opens Google and enters the query. The search engine returns a list of all public-facing websites it has indexed that match the pattern. This provides the attacker with a ready-made list of potential targets, potentially numbering in the thousands. This technique is so prevalent that platforms like Google-Hacking-Database (GHDB) aggregate and categorize these dorks for security researchers and penetration testers to use for authorized security audits. inurl commy indexphp id
That’s why Google and other search engines now throttle or block many dork queries — but they still work to some degree.

For penetration testers (ethical hackers) and system administrators, this pattern is a because of SQL Injection .
This is a GET parameter used to fetch data from a database. For example, index.php?id=5 instructs the database to fetch the article, product, or user profile associated with ID number 5. If the application directly concatenates user input from
: Converts page titles into clean URLs (e.g., "About Us" becomes /about-us ).
: Attackers can alter, delete, or corrupt database contents, leading to data loss or website defacement. The search engine returns a list of all
