## Overview

Admidio is an open-source user management solution. `modules/categories.php` checks that the supplied `type` parameter (`ANN`, `EVT`, `ROL`, `USF`, …) corresponds to a module the actor administers. The follow-up "is this specific category editable by me" check at lines 56-61 is dead code because it compares `$getType` (a category-type code) against mode names (`edit`/`save`/`delete`); the condition is permanently false, so `$category->isEditable()` is never invoked. Prior to version 5.0.10, the `delete`, `sequence`, and `save` switch cases load the category by the supplied UUID and act on it without re-checking that the category belongs to a module the actor administers. A user holding only one module-administrator right can therefore destroy or reorder empty categories belonging to *other* modules — for example, an announcements administrator can delete role categories, profile-field categories, or weblink categories that they have no right to touch. Version 5.0.10 fixes the issue.
