Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
The apache-airflow-providers-keycloak package is vulnerable in versions before 0.7.0. The Keycloak authentication manager did not generate or validate the OAuth 2.0 state parameter and did not use PKCE during login. An attacker with a Keycloak account in the same realm could send a crafted callback URL to a victim, logging the victim into the attacker's Airflow session, where credentials the victim later stores in Airflow Connections could be captured. Upgrade to version 0.7.0 or later.
