## What is CVE-2026-47233?

CVE-2026-47233 is a medium-severity missing authorization vulnerability in admidio, published on 12 Aug 2026. Any signed-in user can exploit it over the network, with no action from the victim.

### Official description

Admidio is an open-source user management solution. Version 5.0.9 added a missing `isAdministratorInventory()` gate to `case 'item_delete':` in `modules/inventory.php`. The same fix was not applied to the sibling `case 'field_delete':` handler, which destroys an entire inventory field definition, cascading to every `adm_inventory_item_data` row that referenced that field and every `adm_inventory_field_options` entry. The handler validates only a session-bound CSRF token; there is no `isAdministratorInventory()` check at the controller level, and `Admidio\Inventory\Entity\ItemField::delete()` does not enforce one at the entity level either (unlike its sibling `ItemField::save()`, which does check `$gCurrentUser->isAdministrator()`). Any user who can log in to the site can permanently destroy a non-system inventory field by sending one POST. Version 5.0.10 provides an updated fix.

Weakness: CWE-862 (Missing Authorization), CWE-1281 (Sequence of Processor Instructions Leads to Unexpected Behavior)

Task:
1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.
2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.
3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.
4. Run the tests and summarise what changed and why.
5. If nothing in the project is affected, say so and change nothing.
