CVE-2026-86792: Apache Airflow Apache Kafka provider: Connection-editor remote code execution on the Scheduler via Kafka connection callback configuration
Apache Airflow Kafka provider 1.15.0 before 2.0.0 resolves unvalidated dotted-path strings into Python callables, enabling Scheduler RCE.
CVE-2026-86792 (moderate) affects apache-airflow-providers-apache-kafka versions 1.15.0 before 2.0.0. Dotted-path strings in a Kafka connection's extra field are resolved into Python callables via import_string with no allowlist, then invoked by the confluent-kafka client. This allows someone with Kafka connection configuration access to achieve remote code execution on the Airflow Scheduler; upgrading to 2.0.0 resolves it.

CVE-2026-76187: Apache Airflow Keycloak provider: Any realm client's credentials mint an Airflow session JWT
Apache Airflow Keycloak provider before 0.10.0 lets any confidential client's credentials in the realm mint an Airflow session JWT.
CVE-2026-76187 affects apache-airflow-providers-keycloak before 0.10.0. 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 credentials of an unrelated application can obtain an Airflow session JWT. Severity is rated moderate.

CVE-2026-86466: Apache Airflow FAB provider: FAB Authentik provider: id_token issuer/audience not validated
Apache Airflow FAB provider before 3.9.0 skips issuer/audience validation on Authentik id_tokens, allowing tokens minted for other clients to authenticate to Airflow.
CVE-2026-86466 affects apache-airflow-providers-fab before 3.9.0. The Authentik OAuth path in the FAB auth manager does not validate the issuer or audience claims of accepted id_tokens. An attacker holding a token minted by the same Authentik identity provider for a different client application can present it to Airflow and be authenticated. Severity is rated moderate by the reporter.

CVE-2026-86465: Apache Airflow Akeyless provider: Akeyless secrets backend: team-scope guard bypass via user-controlled key
Apache Airflow Akeyless provider before 0.3.1 lets DAG authors bypass team-scope guards and read other teams' secrets.
CVE-2026-86465 (moderate) affects apache-airflow-providers-akeyless before 0.3.1. The Akeyless secrets backend's team-scope guard can be bypassed with a user-controlled key: in multi-team deployments, a DAG author scoped to one team can supply a Variable key containing a path separator that resolves a secret belonging to another team.

CVE-2026-82310: Apache Airflow FAB provider: FAB auth manager: deactivated users retain and renew Core API JWT access
Apache Airflow FAB provider 2.0.0-3.8.x lets deactivated users keep unexpired Core API JWTs and mint replacements indefinitely.
CVE-2026-82310 affects apache-airflow-providers-fab versions 2.0.0 before 3.9.0. Deactivating a user account does not stop tokens issued before deactivation. While password authentication correctly rejects the disabled account, the Core API continues to accept an existing unexpired token naming it and lets that token mint a replacement. Severity is rated moderate.

CVE-2026-75156: Apache Airflow FAB provider: FAB Azure AD OAuth: id_token issuer/audience not validated — cross-tenant authentication bypass
Apache Airflow FAB provider flaw (CVE-2026-75156) lets attackers bypass Azure AD OAuth token validation via unvalidated issuer and audience claims.
Apache Airflow FAB provider versions 3.7.3 through 3.8.0 do not validate the issuer or audience of Azure AD id_tokens during OAuth login, enabling cross-tenant authentication bypass. The issue affects deployments where the FAB auth manager is configured with Azure AD as an OAuth provider. A fix is available in version 3.8.1. Severity is rated moderate.
