# CVE-2026-111452: Apache Airflow: Secrets masker: camelCase key names (privateKey, connectionString, webhookUrl) not matched against the sensitive-field list

Status: published. Published: 2026-11-09. Updated: 2026-11-09.

Apache Airflow's secrets masker matched sensitive key names only in their snake_case form, so values stored under camelCase keys such as `privateKey`, `connectionString`, `webhookUrl` or `accessKey` — for example in a Connection's extra or a Variable — were not redacted in task logs, rendered template fields or API responses. A user who can read task logs or rendered templates, but is not meant to see those credentials, could read them in cleartext. Users are advised to upgrade to apache-airflow 3.4.0 or later.
