Information Disclosure in apache-airflow (CVE-2026-45192)
Summary
Vulnerability in apache-airflow (CVE-2026-45192). Confidential information can be exposed externally. Exploitable via extra. Mitigation: upgrade to 3.2.2 or later.
Original description
The description as published by the source.
A bug in the GET /api/v2/connections/{connection_id} REST API endpoint in Apache Airflow allowed an authenticated UI/API user with Connection-read permission to retrieve secrets stored in a Connection's extra JSON blob under field names not present in the redaction allowlist (DEFAULT_SENSITIVE_FIELDS) — for example, official Slack-provider credential field names were returned in plaintext. Affects deployments that store credentials in Connection extra blobs and grant Connection-read access to multiple users. Users are advised to upgrade to apache-airflow 3.2.2 or later. As a defense-in-depth mitigation, deployment operators can store sensitive credential values in a secret-backend rather than inlined into the Connection's extra field.
