# Apache Airflow: camelCase secret keys leak into logs and API responses

Link for people: https://infrastack.ai/live/CVE-2026-111452 (this .md is for agents)

Airflow's secrets masker only redacted sensitive key names written in snake_case, so values under keys like privateKey or connectionString were shown in cleartext. A user who can read task logs, rendered templates or the API, but should not see those credentials, can read them.

_Summary, check and fix written by a model from the sources; labelled as such._

## How to check

- Check the installed version with `airflow version` or `pip show apache-airflow`
- Review Connection extras and Variables for camelCase keys such as `privateKey`, `connectionString`, `webhookUrl` or `accessKey`

## Fix

- apache-airflow `3.4.0` or later

## From the sources

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.
