## Technical details

The importTemplate function in src/services/templateService.ts failed to properly enforce privilege checks, allowing remote attackers to bypass authorization controls. The vulnerability was fixed by adding isPrivilegedServerConfig validation to the template import logic, as shown in patch 18a4467bc4ec6390b1f841d8a468a37e9922f837. Network access to the template import endpoint was required for exploitation.
