Summary

A vulnerability in Maxun before version 0.0.42 allows authenticated users to access other users' robots and OAuth tokens by bypassing ownership checks in storage and webhook API handlers. Attackers can read plaintext Google and Airtable access tokens, modify, delete, or execute other users' robots.

Risk Assessment

The risk includes exposure of sensitive authentication credentials (OAuth tokens) and unauthorized access to resources of other tenants in a multi-tenant environment, potentially leading to data confidentiality and integrity breaches.

Recommendation

Immediately upgrade Maxun to version 0.0.42 or later, which includes fixes for the IDOR vulnerability. Additionally, rotate all Google and Airtable OAuth tokens that may have been exposed.
