CVE-2021-23186Network attack vector

Cross-tenant data access via exposed registry methods

Published Apr 25, 2023 · Updated Aug 3, 2024

Sandbox escape in Odoo Community and Enterprise 15.0 and earlier allows remote authenticated users to read or modify other tenants' data. Core registry instances retained registry-management methods after initialization, enabling crafted requests to reach registries for other databases on the same server. Exploitation requires administrator rights within one tenant and a multi-tenant deployment; it permits cross-tenant database reads and writes without reported service interruption.
