CVE-2026-27173
JWT tokens that were used by workers in Kubernetes Executors have been exposed to users who had read only access to Kuberentes Pods. This could allow users with just read-only access to perform actions that were only available to running tasks via Task SDK and potentially allow to modify state of...
CVE-2026-33858
Dag Authors, who normally should not be able to execute code in the webserver context could craft XCom payload causing the webserver to execute arbitrary code. Since Dag Authors are already highly trusted, severity of this issue is Low. Users are recommended to upgrade to Apache Airflow 3.2.0,...
CVE-2026-42360
A bug in Apache Airflow's rendered-template field handling caused nested sensitive-key masking e.g. nested password / token / secret / apikey keys inside a JSON template structure to be bypassed when the rendered field exceeded core maxtemplatedfieldlength: Airflow stringified the structure befor...
CVE-2026-40963
The structuredata endpoint in the Airflow UI returned external dependency graph nodes for linked Dags without checking whether the caller had read permission on those linked Dags. An authenticated UI/API user authorized for one Dag could enumerate linked Dag IDs and dependency metadata for other...
BIT-AIRFLOW-2026-49298 Apache Airflow: JWT Token Exposure in KubernetesExecutor Command-Line Arguments
A bug in Apache Airflow's KubernetesExecutor caused JWT tokens used by worker pods to authenticate against the Execution API to be passed to the worker container as command-line arguments visible in the pod spec. An authenticated UI/API user with Kubernetes read-only access to the cluster e.g...
BIT-AIRFLOW-2026-49267 Apache Airflow: No certificate validation on SMTP STARTTLS connections
Apache Airflow's EmailOperator and the underlying airflow.utils.email helpers established SMTP STARTTLS connections without verifying the remote certificate when the deployment used email smtpstarttls=True without email smtpssl. An attacker positioned between the worker and the configured SMTP...
BIT-AIRFLOW-2026-48726 Apache Airflow: revoke_token() unreachable in FabAuthManager / KeycloakAuthManager logout path
A bug in Apache Airflow's auth manager logout handling left previously-issued JWT tokens valid after the user clicked logout in the UI: the logout flow for FabAuthManager and KeycloakAuthManager did not actually reach the underlying revoketoken call, so the JWT remained accepted by the API server...
BIT-AIRFLOW-2026-45426 Apache Airflow: Log server JWT authorization bypass via Python lstrip() character stripping allows cross-Dag log access
Exploitation requires the attacker to already be an authenticated Airflow worker holding a valid Log-server JWT issued for at least one Dag. Apache Airflow's Log server authorized JWT tokens against Dag IDs by applying Python's str.lstrip to the requested path segment when verifying the JWT's sub...
BIT-AIRFLOW-2026-45360 Apache Airflow: Arbitrary import in custom deadline-reference deserialization
Apache Airflow's scheduler-side deadline-reference decoder SerializedCustomReference.deserializereference imported and dispatched arbitrary class paths drawn from DAG-author-controlled serialized state without an allowlist or plugin-registry gate. A DAG author whose code reaches the scheduler — t...
BIT-AIRFLOW-2026-45192 Apache Airflow: Incomplete Redaction of Sensitive Fields in Connection Extra API Response
A bug in the GET /api/v2/connections/connectionid REST API endpoint in Apache Airflow allowed an authenticated UI/API user with Connection-read permission to retrieve secrets stored in a Connection's extra JSON blob under field names not present in the redaction allowlist DEFAULTSENSITIVEFIELDS —...
BIT-AIRFLOW-2026-42360 Apache Airflow: Rendered template truncation bypasses nested sensitive-key masking
A bug in Apache Airflow's rendered-template field handling caused nested sensitive-key masking e.g. nested password / token / secret / apikey keys inside a JSON template structure to be bypassed when the rendered field exceeded core maxtemplatedfieldlength: Airflow stringified the structure befor...
BIT-AIRFLOW-2026-42359 Apache Airflow: Authenticated RCE via XCom PATCH endpoint — XComUpdateBody missing FORBIDDEN_XCOM_KEYS validator
A bug in Apache Airflow's XCom PATCH endpoint PATCH /api/v2/xcomEntries/key allowed an authenticated UI/API user with XCom write permission on a Dag to set XCom entries under reserved key names e.g. returnvalue that the matching POST endpoint already validated against FORBIDDENXCOMKEYS. The...
BIT-AIRFLOW-2026-42358 Apache Airflow: Variable masker depth-limit bypass returns cleartext nested secrets
A bug in Apache Airflow's Variable response masker caused nested-key redaction triggered by secret-suffixed key names like password, token, secret, apikey to be bypassed when the JSON value's nesting depth exceeded the shared secrets masker's recursion limit: the masker returned the original nest...
BIT-AIRFLOW-2026-41084 Apache Airflow: API authorization bypass: bulk TaskInstances allows cross-DAG mutation
A bug in Apache Airflow's bulk Task Instances API PATCH/DELETE /api/v2/dags/dagid/dagRuns/dagrunid/taskInstances evaluated authorization against the dagid resolved from the URL path while operating on the dagid / dagrunid extracted from request-body entity fields. An authenticated UI/API user wit...
BIT-AIRFLOW-2026-41017 Apache Airflow: JWT cookie missing Secure flag in JWTRefreshMiddleware behind HTTPS-terminating proxy
Apache Airflow's JWTRefreshMiddleware set the JWT auth cookie without the Secure flag, so deployments running the Airflow API server behind an HTTPS-terminating reverse proxy e.g. nginx / Envoy / a managed load balancer that terminates TLS and forwards plaintext to the API server, the default...
BIT-AIRFLOW-2026-41014 Apache Airflow: per-DAG RBAC bypass on /ui/partitioned_dag_runs endpoints
The partitioneddagruns endpoints in the Airflow UI enforced only asset-level access control, not per-Dag authorization. An authenticated UI/API user with global Asset:read permission could enumerate partition run state, schedule configuration, and asset wiring for Dags they were not authorized to...
BIT-AIRFLOW-2026-40963 Apache Airflow: DAG authorization bypass on /ui/structure/structure_data
The structuredata endpoint in the Airflow UI returned external dependency graph nodes for linked Dags without checking whether the caller had read permission on those linked Dags. An authenticated UI/API user authorized for one Dag could enumerate linked Dag IDs and dependency metadata for other...
BIT-AIRFLOW-2026-40961 Apache Airflow: Open Redirect Bypass Vulnerability
A bug in the login redirect route in Apache Airflow allowed authenticated users to craft URLs that bypassed the issafeurl check, enabling redirection from a trusted Airflow domain to an attacker-controlled origin. Users are advised to upgrade to apache-airflow 3.2.2 or later. As a defense-in-dept...
BIT-AIRFLOW-2026-40861 Apache Airflow: Arbitrary File Read via Log Symlink following in FileTaskHandler
A Dag author could either a create a symlink under their task's log directory pointing to an arbitrary file readable by the API server process read-path attack — e.g. /etc/passwd or airflow.cfg or b supply a taskid containing .. sequences accepted by the Task SDK's KEYREGEX write-path attack, and...
