Incorrect Organization Membership Assignment on Invitation Acceptance

### Environment SaaS ([https://sentry.io/](<https://sentry.io/>)) # Incorrect Organization Membership Assignment on Invitation Acceptance **Issue:** When a user is logged in with their account from organization X (with email X), and they receive an invitation to join organization Y via email Y, upon accepting the invitation, the system adds the user to organization Y with their email X instead of email Y. --- ## Steps to Reproduce: 1. Log in to your account using **organization X** with email **X**. 2. Receive an invitation to join **organization Y** at email **Y**. 3. Follow the invitation link to join **organization Y**. 4.

In either case, the system should prevent membership to **organization Y** being created under the incorrect email **X**. ## Actual Behavior: * The user is added to **organization Y** using the logged-in email **X** (from **organization X**) instead of the invited email **Y**, leading to incorrect account associations. --- ## Severity: * High: This bug results in incorrect organizational membership and potential access control issues.
