{"id":"CVE-2026-75158","published":"2026-09-21T15:17:31.360","lastModified":"2026-09-21T19:17:09.580","description":"Apache Airflow's `/assets/events` API returned asset events for every Dag in the deployment, with no filter restricting them to the Dags the caller is authorized to read. Any authenticated user holding asset-read access could therefore enumerate asset events — including the source Dag ID, task ID, run ID and event timestamps — for Dags they have no permission to see. Because the filter was also absent from the count query, `total_entries` and pagination disclosed the existence of hidden Dags even without inspecting individual rows. Deployments are affected whenever per-Dag access control is used to separate teams or tenants; no special configuration is required. Upgrade to apache-airflow 3.3.2 or later.","cvssScore":4.3,"cvssSeverity":"MEDIUM","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N","cwes":["CWE-200"],"vendors":[],"products":[],"references":[{"url":"https://github.com/apache/airflow/pull/71741","tags":[]},{"url":"https://lists.apache.org/thread/rx5lg86l0qkjl2s7dtmpqxjq0xplr4fy","tags":[]},{"url":"http://www.openwall.com/lists/oss-security/2026/09/21/3","tags":[]}],"exploitRefs":[{"url":"https://github.com/apache/airflow/pull/71741","tags":[]}],"hasPoc":true,"ai":{"summary":"The flaw allows any authenticated user with asset-read access to enumerate asset events for all Dags in the deployment, including those they are not authorized to see, due to missing access control filters.","exploitability":"Exploitation is relatively easy as long as an attacker has basic authentication and asset-read permissions. Precondition is the presence of per-Dag access control.","blast_radius":"If exploited, it could reveal sensitive information about Dags not accessible to the user, potentially leading to unauthorized access or data exposure.","remediation":"Upgrade Apache Airflow to version 3.3.2 or later to apply necessary access control filters.","tags":["auth-bypass","api-exploit","info-leak","web"],"model":"qwen2.5:7b-instruct","analyzedAt":"2026-09-22T06:32:38.123Z"}}
