CVE-2026-96806 (GCVE-0-2026-96806)
Vulnerability from cvelistv5

CWE
  • CWE-613 - Insufficient Session Expiration
Summary
The Apache Airflow Keycloak auth manager did not end the session on logout: the logout route revoked the presented token, but `KeycloakJWTMiddleware` then issued a new, unrevoked token on the same response, so the user stayed logged in. Deployments using the Keycloak auth manager are affected: after a user logs out, anyone with later access to the same browser (for example on a shared workstation) can continue to act as that user. Users of apache-airflow-providers-keycloak are recommended to upgrade to apache-airflow-providers-keycloak 0.11.1 or later.

CWE
  • CWE-732 - Incorrect Permission Assignment for Critical Resource
Summary
The Apache Airflow Keycloak provider's multi-team provisioning (`_attach_team_permissions`) granted every team role global read access to audit logs. Deployments that enable multi-team mode with the Keycloak auth manager and provision teams through it are affected: any authenticated member of one team could read other teams' audit events through the UI or the event-log API. Users of apache-airflow-providers-keycloak are recommended to upgrade to apache-airflow-providers-keycloak 0.11.1 or later.

CVE-2026-76187 (GCVE-0-2026-76187)
Vulnerability from cvelistv5
Published
2026-09-16 09:10
Modified
2026-09-17 19:21
Severity ?
CWE
  • CWE-287 - Improper Authentication
Summary
Apache Airflow Keycloak provider: the unauthenticated token endpoint accepts a client-credentials grant for any confidential client registered in the Keycloak realm, not only the client configured for Airflow. No allowlist restricts which client ids may authenticate, so the credentials of an unrelated application that happens to share the realm are valid Airflow login credentials, and Airflow mints a signed session token for that application's service account. The endpoint also answers unauthenticated credential guesses against Keycloak under Airflow's identity. Affects deployments using the Keycloak auth manager whose realm is shared with other confidential clients. The attacker needs valid credentials for any one of those clients, not for Airflow. Resource authorization is still evaluated per subject, so the access gained is whatever that service account holds, plus any endpoint gated only on being authenticated. Users of apache-airflow-providers-keycloak are recommended to upgrade to version 0.10.0 or later, which accepts only the configured client on that grant.

CVE-2026-76186 (GCVE-0-2026-76186)
Vulnerability from cvelistv5
Published

Severity ?
CWE
  • CWE-565 - Reliance on Cookies without Validation and Integrity Checking in a Security Decision
Summary
Apache Airflow Keycloak provider: from Airflow 3.3 the Keycloak auth manager takes a user's identity from the signed Airflow session token but takes the Keycloak access and refresh tokens used for every authorization decision from separate, unauthenticated cookies, and never checks that the two describe the same subject. A user who holds any valid Airflow login of their own, together with another subject's Keycloak access or refresh token obtained out of band, can pair the two: Airflow then authorizes requests with the foreign token's privileges while the session identity, audit log and cache keys continue to name the attacker's own account. The refresh path re-issues an Airflow session token for the original identity carrying the foreign tokens, so the mismatched pairing survives across sessions. Affects deployments running Airflow 3.3 or later with the Keycloak auth manager. Earlier versions carried the Keycloak tokens inside the signed session token, so the binding existed and was lost when they moved into separate cookies. Users of apache-airflow-providers-keycloak are recommended to upgrade to version 0.10.0 or later, which binds the cookie-supplied tokens to the session identity.
