Doc Text:
A flaw was found in Apache OFBiz. In multitenant environments, the application attempts to resolve tenant delegator names from user-supplied parameters before confirming that the specified tenant actually exists. Because internal resolution requests are retained in an internal cache even when invalid, an unauthenticated remote attacker can submit arbitrary tenant identifiers to cause unbounded cache growth, leading to severe memory and database resource exhaustion and a potential Denial of Service (DoS).

Description OSIDB Bzimport 2026-11-05 21:59:50 UTC 
In multitenant deployments, ContextFilter and LoginWorker built a per-tenant delegator name from a request-supplied userTenantId parameter and requested a delegator for it before confirming the tenant existed. DelegatorFactory's internal cache retains every delegator name it is asked to resolve, including ones that fail to resolve, so an unauthenticated attacker could submit a stream of arbitrary tenant IDs to grow this cache without bound, driving unnecessary memory and database load.
