CVE-2026-68970 (GCVE-0-2026-68970)

Vulnerability from cvelistv5 – Published: 2026-08-12 15:24 – Updated: 2026-09-16 14:57

Title

Apache Airflow: Values of a list-shaped Variable are not masked in task logs and the Rendered Templates UI

Summary

Apache Airflow's Task SDK did not mask the contents of a Variable whose JSON value is a list, so secrets stored in that shape appeared in cleartext in task logs and in the Rendered Templates UI. Masking was applied only when the deserialized value was a string or a dict; a list at the top level matched neither and was returned unmasked. Any authenticated user able to read the logs or rendered templates of a task that references such a Variable could recover the values, with no special configuration required. This is the list-shaped counterpart of CVE-2026-59244, whose fix covered the dict case only, so deployments that upgraded in response to that advisory remain affected and must upgrade again. Users are advised to upgrade to apache-airflow 3.3.1 or later.

Severity
