### Official description

This module enables you to use the media library in custom forms without the Media Library Widget.

The module does not properly check entity access in some circumstances. This may result in users with access to edit content seeing metadata about media items they are not authorized to access.

The vulnerability is mitigated by the fact that the inaccessible media will only be visible to users who can already edit content that includes a media reference field.

What it is: DRUPAL-CONTRIB-2023-004 is a vulnerability in drupal/media_library_form_element, published on 18 Jan 2023. Any signed-in user can exploit it over the network, with no action from the victim.
Exploitation: There is no known exploitation of DRUPAL-CONTRIB-2023-004 in the wild and no public exploit code.

Affected product: drupal/media_library_form_element. No package-level version data is available, so check the vendor advisory linked from the reference page.

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.
