CVE-2026-74841— Apache OFBiz: Denial of Service via unauthenticated userTenantId in multitenant mode

Quick assessment

Affected
Apache Software Foundation Apache OFBiz
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

在多租户部署环境中，ContextFilter 和 LoginWorker 会依据请求中提供的 userTenantId 参数构建每个租户的代理（delegator）名称，并在确认该租户确实存在之前，就向 DelegatorFactory 请求对应的代理对象。由于 DelegatorFactory 的内部缓存会保留所有被请求解析的代理名称（包括那些解析失败的名称），未认证的攻击者可以提交任意租户 ID 的连续请求，导致该缓存无限制增长，从而引发不必要的内存消耗和数据库负载。

Vulnerability Title
Apache OFBiz: Denial of Service via unauthenticated userTenantId in multitenant mode
Source: CVE Program / CVE List V5
Vulnerability Description
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.
