Low-privilege credential disclosure via unredacted datasource listing
Published Jun 30, 2026 · Updated Jun 30, 2026
Missing authorization in CCF Open Source Nightingale before 9.0.0-beta.2 allows remote authenticated users to read datasource credentials. The datasource list handler returns full Datasource objects without applying RedactSecrets to non-admin responses, exposing settings, HTTP headers, authentication data, and mTLS client keys. Standard-role access is sufficient, and the disclosed credentials grant access to connected downstream systems.
