CVE-2026-46427 | Budibase: Snowflake private key returned unmasked from datasource API to BASIC users

Budibase is an open-source low-code platform. Prior to 3.38.3, removeSecrets at packages/server/src/sdk/workspace/datasources/datasources.ts masks only datasource config fields whose schema type is DatasourceFieldType.PASSWORD. The Snowflake integration types its privateKey field as SENSITIVE_LONGFORM, which the filter skips. GET /api/datasources/:datasourceId lives on authorizedRoutes guarded by PermissionType.TABLE + PermissionLevel.READ. An authenticated BASIC user with any app role and call the endpoint and receive the full Snowflake PEM in plaintext. This vulnerability is fixed in 3.38.3.
