Secret disclosure via shallow nested-variable redaction
Published Apr 18, 2026 · Updated Apr 18, 2026
Information disclosure in Apache Airflow 3.0.0 and later before 3.2.0 allows remote attackers to read secrets from nested JSON Variables. VariableResponse.redact_val parses a Variable value as JSON but passes it to redact with max_depth=1, leaving sensitive-key values below that depth unmasked. Exposure requires a stored JSON Variable with nested sensitive values and a request that retrieves it; the reported consequence is disclosure only.

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.
