CVE-2025-27555Network attack vectorHinoki check available

Connection-secret disclosure via unmasked CLI audit logs

Published Feb 24, 2026 · Updated Feb 24, 2026

Information disclosure in Apache Airflow before 2.11.1 allows remote authenticated users with audit-log access to read connection secrets. The CLI audit-metrics builder records complete --conn-json and --conn-uri arguments in the log table without masking passwords or sensitive keys. Exposure requires a connection to be added through those CLI forms and audit-log access; disclosed values can grant access to connected systems.
