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.
