A vulnerability was identified in zsadmin2025 ZS-Admin up to b52e14536d59fda11e56e2536a1c32e82a38cead. This affects the function getTenantId of the file /api/system/sys/dept/page of the component MyBatis-Plus Tenant Plugin. Such manipulation of the argument X-Tenant-Id leads to authorization bypass. The attack may be performed from remote. The exploit is publicly available and might be used. This product utilizes a rolling release system for continuous delivery, and as such, version information for affected or updated releases is not disclosed. The project was informed of the problem early through an issue report but has not responded yet.
