CVE-2023-45348Network attack vector

Sensitive configuration disclosure via case-mismatched API keys

Published Oct 14, 2023 · Updated Feb 13, 2025

Information exposure in Apache Airflow 2.7.0 through 2.7.1 allows remote authenticated users to read sensitive configuration via the REST API. The configuration endpoint compares attacker-supplied section and option names to a lowercase sensitive-value set without normalizing their case, so mixed-case names bypass masking. Exposure requires expose_config=non-sensitive-only, a non-default setting, and valid Airflow credentials; the flaw discloses individual configuration values.
