CVE-2026-65017: CWE-200: Exposure of Sensitive Information to an Unauthorized Actor in Apache Software Foundation Apache Airflow
Apache Airflow's Config API did not mask team-scoped sensitive configuration values in multi-team deployments. When an administrator has enabled multi-team mode and exposed the Config API, an authenticated Viewer holding only configuration-read access — with no prior access to the secret — could read a team-scoped Celery broker URL, including its embedded credentials, in cleartext, while the equivalent global option was correctly masked. The secrets masker matched only base section and option names and did not normalize team-prefixed sections before the sensitivity check (CWE-200). This is a distinct masker bypass from CVE-2026-48828 and CVE-2026-48892: deployments that upgraded to apache-airflow 3.3.0 to address those issues remain affected by this team-scoped variant. Users are advised to upgrade to apache-airflow 3.3.1 or later, which normalizes team-scoped sections before masking.
AI Analysis
Technical Summary
Apache Airflow's Config API in version 3.3.0 does not properly mask sensitive team-scoped configuration values when multi-team mode is enabled. An authenticated user with configuration-read access but no prior access to secrets can read team-scoped Celery broker URLs containing embedded credentials in cleartext. The root cause is that the secrets masker only matches base section and option names without normalizing team-prefixed sections, leading to a CWE-200 exposure of sensitive information. This vulnerability is distinct from previous masker bypasses (CVE-2026-48828 and CVE-2026-48892) and affects deployments upgraded to 3.3.0 to address those earlier issues. The issue is resolved in version 3.3.1 by normalizing team-scoped sections before applying masking.
Potential Impact
Sensitive configuration information, specifically team-scoped Celery broker URLs with embedded credentials, can be exposed in cleartext to authenticated users who have only configuration-read access and no prior secret access. This exposure could lead to unauthorized access to sensitive infrastructure components if the credentials are used maliciously. The global configuration options remain properly masked, limiting the scope to team-scoped configurations.
Mitigation Recommendations
Users should upgrade Apache Airflow to version 3.3.1 or later, which includes a fix that normalizes team-scoped sections before masking sensitive information. There is no indication of an official patch or temporary workaround other than upgrading. Since this vulnerability affects only version 3.3.0, avoiding use of that version or upgrading promptly is recommended.
