Using Single Sign-On (SSO) with Google Cloud is a smart choice for organizations. It improves security and makes user authentication easier. SSO centralizes authentication through a trusted Identity Provider (IdP), reducing risks. It also makes it easier for IT teams to manage user access and enforce security policies, including multi-factor authentication (MFA).

To transition smoothly to SSO, organizations should follow these steps: select a compatible IdP, configure settings, and thoroughly test the setup. SSO offers several benefits: improved security, better user experience, simplified administration, and compliance with regulatory standards.

Proof of Concept (PoC):
1-Login with Google:

2-Intercept the OAuth Request:

3-Modify the Request:

Change the id field to any ID.
NOTE In changing the ID, you can try any number because it does not verify whether this number is correct or not, but it verifies whether the ID existed before or not, so you can enter anything, for example
“id”:”1″ or “id”:”123456”…. etc
Change the email field to the victim’s email address.

     here can reset request

4- now Gain Access to Victim’s Account:

Conclusion
This situation shows how a vulnerability can be used to take over accounts without any action from the user. It is important to fix this problem quickly to protect user data and the reputation of Example.com.
