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 3.3.2 has an authorization weakness, allowing authenticated users with edit permission on one Dag and read access to others to delete queued events of every readable Dag. The impact is suppression of asset-triggered runs of Dags they cannot edit. Users should upgrade to 3.4.0 or later.

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

Original source description

Read the full publisher description

Apache Airflow's API endpoint for deleting an asset's queued events checked Dag edit permission against the dag_id query parameter, but deleted the queued events of every Dag the caller could read. An authenticated user with edit permission on one Dag and read access to others could suppress asset-triggered runs of Dags they cannot edit. This is an incomplete fix for CVE-2026-75157: users who upgraded to apache-airflow 3.3.2 for that fix are still affected and should upgrade to apache-airflow 3.4.0 or later.
