Authenticated cross-tenant compromise via credential disclosure
Published Aug 6, 2026 · Updated Aug 6, 2026
Sensitive information exposure in OpenReception before 1.0.2 allows remote authenticated users to obtain PostgreSQL credentials. The tenant GET handler serializes the complete tenant database row, including its live databaseUrl, instead of projecting an allowlisted response. A TENANT_ADMIN who can reach PostgreSQL can bypass tenant isolation to read, modify, or delete other tenants' data; superuser credentials also expose the database container.
