Vulnerability details
The vulnerability allows a remote attacker to sign a victim into an attacker-controlled account, causing the victim's subsequent actions and submitted data to be associated with that account.
The vulnerability exists due to missing session-bound state validation in the Apache Camel OAuth authorization code callback when processing authorization responses. A remote attacker can trick a victim into submitting a callback containing an authorization code obtained in another browser to associate the attacker-controlled identity with the victim's session.
