Description

Snipe-IT is an IT asset/license management system. Prior to 8.6.0, UsersController::update() passes a missing permission request field through NormalizePermissionsPayloadAction and PreserveUnauthorizedPrivilegedPermissionsAction in a way that can overwrite a target user’s permissions with a sparse result, allowing an administrator updating another administrator, or a user with users.edit updating a regular account, to remove the target’s administrative or granular permissions. This issue is fixed in version 8.6.0.
