{"cve":"CVE-2026-45192","nvd":{"published":"2026-06-01T08:16:20.567","modified":"2026-07-21T18:10:00.117","status":"Analyzed","description":"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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N","score":6.5},"cwes":["CWE-200"],"references":["https://github.com/apache/airflow/pull/66673","https://lists.apache.org/thread/r2q93dg2wp5h9sd9vh6y4y5ljqd9crdd","http://www.openwall.com/lists/oss-security/2026/06/01/3"],"products":["apache:airflow"],"source":"nvd","synced_at":"2026-10-19T22:37:48.043517290+00:00"},"epss":{"cve":"CVE-2026-45192","score":0.00425,"percentile":0.36822,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-2883-wwh7-x57v","url":"https://osv.dev/vulnerability/GHSA-2883-wwh7-x57v","summary":"Apache Airflow: Incomplete redaction allowlist exposes secrets in Connection `extra`  to read-permitted users","modified":"2026-07-08T00:11:13.633208902Z","packages":[{"ecosystem":"PyPI","name":"apache-airflow","purl":"pkg:pypi/apache-airflow","ranges":["<3.2.2"],"fixed":["3.2.2"]}]},{"id":"PYSEC-2026-173","url":"https://osv.dev/vulnerability/PYSEC-2026-173","summary":"","modified":"2026-07-13T16:45:04.896592258Z","packages":[{"ecosystem":"PyPI","name":"apache-airflow","purl":"pkg:pypi/apache-airflow","ranges":["<3.2.2"],"fixed":["3.2.2"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
