description

eneo versions before 2.2.0 can authorize a tenant-scoped service API key to access shared spaces belonging to another tenant. An attacker who possesses such a key can view or modify another tenant's shared-space data; personal spaces are not affected.

mitigation

Upgrade eneo to version 2.2.0 or later. Until upgraded, restrict issuance and access to tenant-scoped service API keys to reduce exposure.

fixed in 2.2.0
