Description

A flaw was found in Ansible Lightspeed. This vulnerability, related to insufficient session expiration, allows a remote attacker to maintain persistent access to the Ansible Lightspeed instance. If an attacker exfiltrates a valid OAuth (Open Authorization) access token before a user logs out, they can continue to authenticate and access sensitive data. This is because the application fails to invalidate the token on the backend, leaving it valid until its natural expiration. This can lead to unauthorized read access to Ansible resources such as inventories, playbooks, and configuration data.
