CyberRota Analysis
AI-GeneratedApache Airflow's secrets masker is vulnerable due to a recursion-depth limit that fails to mask deeply-nested values within lists, tuples, or sets, allowing sensitive data to be displayed unmasked in the UI. While the exposure is limited to authenticated users who can already access the full value via the Variables REST API, this issue represents a potential risk for shoulder-surfing attacks. Organizations using Apache Airflow, particularly those that have previously applied the fix for CVE-2026-42358, should prioritize upgrading to version 3.3.1 or later to mitigate this vulnerability.

Original NVD Description
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.
