Vulnerability Title
FUXA Business Logic Flaw: Role Deletion Without User Assignment Cleanup
Source: CVE Program / CVE List V5
Vulnerability Description
FUXA is a web-based Process Visualization (SCADA/HMI/Dashboard) software. Prior to 1.3.3, DELETE /api/roles removes role definitions through server/runtime/users/usrstorage.js but does not remove the deleted role identifier from each user's info.roles array or the runtime usersMap cache. If a permission configuration still references that identifier, an affected user can retain authorization rights that an administrator intended to revoke, causing residual privilege, inconsistent access-control state, and misleading audit results. This issue is fixed in version 1.3.3.
