- A
Stored XSS; risk of data theft from database
Why wrong: Stored XSS persists in the database, but this scenario describes reflected XSS.
- B
Reflected XSS; risk of session hijacking
Reflected XSS allows attackers to execute scripts in the victim's browser, often to steal cookies/sessions.
- C
Blind XSS; risk of internal network scanning
Why wrong: Blind XSS is a type of stored XSS that triggers in a different context, not reflected.
- D
DOM-based XSS; risk of client-side logic bypass
Why wrong: DOM-based XSS occurs in the client-side script, not server-side reflection.
