CVE-2026-84728
Full vulnerability record from the local CVENow database.
Description
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.
