Vulnerability details

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.

MITRE ATT&CK Enterprise TechniquesAI

T1033 System Owner/User Discovery Discovery
Adversaries may attempt to identify the primary user, currently logged in user, set of users that commonly uses a system, or whether a user is actively using the system.
T1078.004 Cloud Accounts Stealth
Valid accounts in cloud environments may allow adversaries to perform actions to achieve Initial Access, Persistence, Privilege Escalation, or Defense Evasion.
T1087.004 Cloud Account Discovery
Adversaries may attempt to get a listing of cloud accounts.
T1685.002 Disable or Modify Cloud Log Defense Impairment
An adversary may disable or modify cloud logging capabilities and integrations to limit what data is collected on their activities and avoid detection.
Why these techniques?

The vulnerability enables reuse of invalidation-failed authorization tokens post-user removal, facilitating unauthorized user discovery (T1033, T1087.004), persistence via valid cloud accounts (T1078.004), and modification/deletion of cloud logs (T1562.008).
