## What is CVE-2026-47226?

CVE-2026-47226 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. Prior to version 5.0.10, an authenticated Admidio member with upload rights on any one folder can permanently delete files from folders where they have only view access. The authorization check at the top of `modules/documents-files.php` evaluates upload rights against the attacker-supplied `folder_uuid` URL parameter — not the file's actual parent folder. The `file_delete` handler then only verifies view rights on the file's real location, never upload rights. By passing a folder they legitimately own in `folder_uuid` while targeting a file in a restricted folder via `file_uuid`, an attacker bypasses the upload-right check entirely and permanently deletes the file. This is an incomplete fix of GHSA-rmpj-3x5m-9m5f, which was patched in v5.0.7 but remains exploitable in v5.0.9. User should upgrade to v5.0.10 to receive an updated fix.

Weakness: CWE-862 (Missing Authorization), CWE-639 (Authorization Bypass Through User-Controlled Key)

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.
