What is CVE-2026-67442?
CVE-2026-67442 is a low-severity vulnerability in frangoteam FUXA, published on 18 Aug 2026. An attacker needs administrator access to exploit it, and only if a user opens a file or follows a link.
Official 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.
