Vulnerability in airflow (CVE-2026-46764)
Summary
Vulnerability in airflow (CVE-2026-46764). Risk of unauthorized operations or information disclosure. Exploitable via GET /api/v2/eventLogs/{event_log_id}. Mitigation: upgrade to 3.2.2 or later.
Original description
The description as published by the source.
The Event Log detail endpoint GET /api/v2/eventLogs/{event_log_id} in Apache Airflow fetched audit-log rows directly by numeric ID after only the generic Audit Log permission check, while the collection endpoint GET /api/v2/eventLogs applied per-Dag scoping. An authenticated UI/API user with audit-log read permission for one Dag could retrieve audit-log entries for any other Dag by guessing or enumerating the numeric event log ID. Affects deployments that rely on per-Dag audit-log scoping. Users are advised to upgrade to apache-airflow 3.2.2 or later.

A vulnerability (CWE-639) exists in airflow. Attackers reach the vulnerable code path via GET /api/v2/eventLogs/{event_log_id}.
Check the vendor advisory for the affected versions of airflow. Attack surface: GET /api/v2/eventLogs/{event_log_id} / GET /api/v2/eventLogs.
Severity: Medium (CVSS 4.3/10). Risk of unauthorized operations or information disclosure.
Update to 3.2.2.
Until the patch is applied: disable the affected feature, apply WAF rules, or restrict access via network ACLs.
Search webserver/proxy logs for unusual GET /api/v2/eventLogs/{event_log_id} requests with malformed payloads or SQL meta-characters. Run grep -r 'airflow' . against your dependency files (package-lock.json, requirements.txt, go.sum) to find affected services.
Response actions
Concrete steps and command examples for SOC/SRE teams to execute in order
-
1Identify exposure identify
grep -r 'airflow' . | grep -v node_modulesリポジトリと本番環境の依存ファイル (package-lock.json / requirements.txt / go.sum / Gemfile.lock 等) で
airflowを grep し、稼働しているサービス・バージョンを把握する。 -
2Hunt for indicators of compromise detect
grep 'GET /api/v2/eventLogs/{event_log_id}' /var/log/nginx/access.log | grep -E '(unusual_payload|sqli_pattern)'アクセスログで
GET /api/v2/eventLogs/{event_log_id}への異常なリクエスト (不正な認証ヘッダ・SQLメタ文字)を過去 30〜90日分捜索。WAF/SIEM があれば該当パスのアラート発火履歴を確認。 -
3Apply patch patch
Upgrade airflow to 3.2.2ステージング環境で 3.2.2 に上げて回帰テスト → 本番反映。回帰テストはアプリの主要ハッピーパスと、Step 2 で見つけた異常検知の続報チェックを含めること。
-
4Post-deployment verification verify
Replay attack against GET /api/v2/eventLogs/{event_log_id} on staging to confirm patch closes the vectorパッチ適用後、ステージングで PoC または同等の悪用パターンを再現して脆弱性が閉じたことを確認。本番では Step 2 と同じログクエリでアラート再発が無いか継続監視。
