Severity

medium6.5

CVSS measures technical severity, not the likelihood of an attack.

Known exploitation

Not listed in the checked CISA KEV catalog

Absence from CISA KEV does not rule out attacks.

Public exploit

Not established by this record

Missing evidence does not mean no public exploit exists.

Remediation

Fix status not established

No structured fix or guidance is available here. Check the latest publisher advisory.

What this means

Apache Airflow's asset API endpoints return Dag IDs without access checks, allowing authenticated users with asset read access to learn IDs of Dags they cannot see. Affected versions include Apache Airflow 2.x and versions before 3.4.0. An authenticated user with asset read access is required to exploit the weakness.

Summarized by @cf/meta/llama-3.3-70b-instruct-fp8-fast. Verify details against the original sources.

What to do

Compare your installed product and version with the affected versions above. A matching product name alone does not confirm exposure.

No structured fix or remediation guidance is available here. Check the full source description and vendor’s latest advisory for a patch or workaround; do not assume another version is safe.

Original source description

Read the full publisher description

Apache Airflow's asset API endpoints returned the IDs of Dags that are scheduled on, produce, or consume an asset without checking whether the caller may read those Dags. An authenticated user with asset read access could learn the IDs of Dags they are not authorized to see. Users are advised to upgrade to apache-airflow 3.4.0 or later. Airflow 2.x is also affected; Airflow 2 has reached end of life and will not receive a fix, so Airflow 2 users should upgrade to Apache Airflow 3.4.0 or later.
