CVE-2026-84728 · Severity: info · Published 2026-11-05

Apache OFBiz is an open-source enterprise resource planning (ERP) system. When multitenancy is enabled, a low-privilege user in one tenant can read and write data from a different tenant by exploiting how login credentials are processed. An attacker can use this to access confidential business data or modify records belonging to other organizations using the same OFBiz instance.

## How to fix

- Fixed in 24.09.08

## Technical details

The vulnerability is an authorization bypass in OFBiz's multitenancy implementation. The ContextFilter resolves the tenant from the hostname via TenantDomainName, but LoginWorker prioritizes a userTenantId request parameter over hostname-based tenant resolution, causing authentication to occur against the attacker's own tenant while subsequent requests perform data operations against the hostname-mapped tenant. This allows an authenticated attacker to access cross-tenant data when a hostname is mapped to a different tenant than their own credentials belong to.

## Affected products
