Executive Summary

The vulnerability in PlaciPy version 1.0.0 arises because the application determines the tenant identifier solely based on the email domain provided by the user, without verifying whether the user actually owns or is authorized to use that domain.

This lack of validation allows an attacker to impersonate another tenant by simply using an email address with that tenant's domain, leading to unauthorized cross-tenant data access.
