Echo: apache-airflow: security update to 3.3.1

medium Tenable Self-Hosted Container Security Plugin ID 472793

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - Apache Airflow's secrets masker hides values stored under sensitive key names when they are displayed in
 the UI. The masker's recursion-depth limit did not descend into values nested inside a list, tuple, or set
 beyond that limit, so an Airflow Variable holding such a deeply-nested value was shown unmasked in the
 Variables UI. The exposure is limited to the UI: any authenticated user who can see the Variable in the UI
 can already read its full value through the Variables REST API, so this does not disclose data the user
 could not otherwise obtain — the masking is a shoulder-surfing defense for the UI, not an access-control
 boundary. This is an incomplete-fix follow-up to CVE-2026-42358, whose fix made only the dictionary walk
 unbounded; lists, tuples, and sets beyond the depth limit remained unmasked in the UI. Deployments that
 applied the CVE-2026-42358 fix should also upgrade to address this residual case. Upgrade to apache-
 airflow 3.3.1 or later. (CVE-2026-54183)

Solution

Update the apache-airflow library and its related packages to version 3.3.1 or later.
