Name of the Vulnerable Software and Affected Versions Apache Airflow versions prior to 3.2.2

Description A bug in the Variable response masker allows the bypass of nested-key redaction when the nesting depth of a JSON value exceeds the recursion limit of the shared secrets masker. This occurs with key names suffixed by secrets, such as password, token, secret, or api key, as the masker returns the original nested item before verifying the sensitive key name. An authenticated UI or API user with Variable read permissions can harvest plaintext secret values stored within deeply-nested JSON Variables.

Recommendations Update to version 3.2.2 or later.
