Authenticated secret disclosure via masker depth cutoff
Published Jun 1, 2026 · Updated Jun 1, 2026
Information disclosure in Apache Airflow before 3.2.2 allows remote authenticated users to read deeply nested Variable secrets. SecretsMasker._redact returns the original item when depth exceeds max_depth before should_hide_value_for_key checks a sensitive key name. Variable read permission and sensitive values nested beyond the default depth of five are required; exposed values can include stored credentials and tokens.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
