What are the common attack vectors for OAuth 2.0?

Common attack vectors for OAuth 2.0 include authorization code interception, token leakage, and CSRF attacks.

Can you explain how authorization code interception works?

Authorization code interception occurs when an attacker intercepts the authorization code during the OAuth flow, allowing them to obtain access tokens.

What measures can be taken to prevent these attacks?

To prevent these attacks, use secure redirect URIs, implement PKCE, and ensure proper validation of tokens.

Are there any real-world examples of these attacks?

Yes, there have been incidents where attackers exploited OAuth vulnerabilities to gain unauthorized access to user accounts.
