apache-airflow-providers-keycloak: Missing OAuth 2.0 State and PKCE Enables Login CSRF and Session Fixation
CVE-2026-40948 · GHSA-5w6h-pjw6-wvc6
- Affected
- PyPI apache-airflow-providers-keycloak >= 0.0.1, < 0.7.0
- Fixed in
- 0.7.0· Vendor fix available
- Issue
- The Keycloak authentication manager in apache-airflow-providers-keycloak did not generate or validate the OAuth 2.0 state parameter on the login / login-callback flow, and did not use PKCE. An attacker with a Keycloak account in the same realm could deliver a crafted callback URL to a victim's browser and cause the victim to be logged into the attacker's Airflow session (login-CSRF / session fixation), where any credentials the victim subsequently stored in Airflow Connections would be harvestable by the attacker. Users are advised to upgrade apache-airflow-providers-keycloak to 0.7.0 or later.
Recommended action: Upgrade to 0.7.0 or later, then redeploy and verify.A vendor fix does not resolve your finding until you verify it in your own systems.
