About CSRF (Cross-Site Request Forgery)
CSRF vulnerabilities occur when an attacker tricks a user into performing unwanted actions on a web application in which they are authenticated. The attack exploits the trust that a site has in the user's browser.
Common CSRF Attack Types
Basic CSRF: Simple form submission attacks using hidden forms or image tags
Token Bypass: Bypassing CSRF protection mechanisms like tokens
File Upload CSRF: Using file upload functionality to perform CSRF attacks
JSON CSRF: Exploiting applications that accept JSON payloads
Advanced Techniques: Complex methods to bypass modern protections
