CVE-2026-84728
Apache OFBiz: Cross-tenant authorization bypass in mapped-domain login
What happened?
Incorrect Authorization in Apache OFBiz 24.09 before 24.09.08 on all platforms, when documented multitenancy is enabled, allows a remote authenticated attacker holding only a valid low-privilege account in one tenant to read and write data belonging to a different tenant, by submitting their own tenant's userTenantId alongside their own credentials to the normal Party Manager login against a hostname mapped to a different tenant: ContextFilter resolves the tenant from the hostname via TenantDomainName, but LoginWorker gives priority to the conflicting userTenantId request parameter and authenticates against the attacker's own tenant, so a subsequent ordinary request to the same hostname combines the hostname-mapped tenant's Entity Engine delegator with the attacker's tenant's session dispatcher, security object, and identity, letting the permission check run against the attacker's own tenant while the resulting read or write is performed against the hostname-mapped tenant's data. Users are recommended to upgrade to version 24.09.08, which fixes this issue.

How to respond
- Confirm the product, installed package version, and any configuration requirements in the vendor advisory.
- Follow the vendor’s remediation or workaround guidance in the references below. Structured fixed-version data is unavailable here; the publisher’s description may include a fix or workaround.
- Restart affected services if required, then verify the running version. Known exploitation may warrant investigation as well as patching.
