CVE-2023-6460

Credential disclosure via serializable settings object

Published Dec 4, 2023 · Updated May 7, 2026

Sensitive-information exposure in Google Cloud Firestore Node.js Client before 6.1.0 allows local users to read service-account keys from logs. The _settings property remained serializable, so JSON.stringify on Firestore objects copied its credentials, including private_key, into log output. Exposure requires an application to log a Firestore object and attackers to have log-read access; the published impact is credential disclosure without integrity or availability loss.
