CVE-2026-48080Public exploitNetwork attack vector

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.
