Technical details
The vulnerability is an information disclosure (CWE-200) caused by improper masking of sensitive configuration values in the Config API when multi-team mode is enabled. The secrets masker performs a direct membership test against registered base section and option names but fails to normalize team-prefixed sections (formatted as `[<team>=<section>]` in config files or `AIRFLOW__<TEAM>___<SECTION>__<KEY>` in environment variables) before applying the sensitivity check. An authenticated user with Viewer role and configuration-read permission can read team-scoped Celery broker URLs with embedded credentials in cleartext, while the same global configuration option is correctly masked. This is distinct from earlier masker bypass vulnerabilities (CVE-2026-48828 and CVE-2026-48892) and affects even deployments that upgraded to version 3.3.0. The fix normalizes team-scoped sections before masking checks; users should upgrade to apache-airflow 3.3.1 or later.
