In lunary-ai/lunary version 1.0.1, a vulnerability exists where a user removed from an organization can still read, create, modify, and delete logs by re-using an old authorization token. The lunary web application communicates with the server using an 'Authorization' token in the browser, which does not properly invalidate upon the user's removal from the organization. This allows the removed user to perform unauthorized actions on logs and access project and external user details without valid permissions.

By knowing an organization's ID, an attacker can join the organization without permission and gain the ability to read and modify all data within that organization. This vulnerability allows unauthorized access and modification of sensitive information, posing a significant security risk. The flaw is due to insufficient verification of user permissions when joining an organization.

An Insecure Direct Object Reference (IDOR) vulnerability exists in the lunary-ai/lunary application version 0.3.0, allowing unauthorized deletion of any organization's project. The vulnerability is due to insufficient authorization checks in the project deletion endpoint, where the endpoint fails to verify if the project ID provided in the request belongs to the requesting user's organization. As a result, an attacker can delete projects belonging to any organization by sending a crafted DELETE request with the target project's ID. This issue affects the project deletion functionality implemented in the projects.delete route.
