Severity

CVSS measures technical severity, not the likelihood of an attack.

Known exploitation

Not listed in the checked CISA KEV catalog

Absence from CISA KEV does not rule out attacks.

Public exploit

Not established by this record

Missing evidence does not mean no public exploit exists.

Remediation

Fix status not established

No structured fix or guidance is available here. Check the latest publisher advisory.

What this means

Apache Airflow's secrets masker does not match camelCase key names, potentially exposing credentials in task logs, template fields, or API responses to users with read access. Affected versions include Apache Airflow 2.x and versions prior to 3.4.0. A user with read access to task logs or templates could read credentials in cleartext.

Summarized by @cf/meta/llama-3.3-70b-instruct-fp8-fast. Verify details against the original sources.

What to do

Compare your installed product and version with the affected versions above. A matching product name alone does not confirm exposure.

No structured fix or remediation guidance is available here. Check the full source description and vendor’s latest advisory for a patch or workaround; do not assume another version is safe.

Original source description

Read the full publisher description

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. Airflow 2.x is also affected; Airflow 2 has reached end of life and will not receive a fix, so Airflow 2 users should upgrade to Apache Airflow 3.4.0 or later.

    Description revised

    before

    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.
