## What is DRUPAL-CONTRIB-2018-008?

DRUPAL-CONTRIB-2018-008 is a cross-site scripting vulnerability in drupal/entity_ref_tab_formatter, published on 7 Feb 2018. Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.

### Official description

This module enables you to show referenced entities in tabs.

The module doesn't sufficiently sanitize the body fields of the referenced entities when it prints them to the tabs.

This vulnerability is mitigated by the fact that an attacker must have a role with the permission create/edit content of the content type that is referenced.

What it is: DRUPAL-CONTRIB-2018-008 is a cross-site scripting vulnerability in drupal/entity_ref_tab_formatter, published on 7 Feb 2018. Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.
Exploitation: There is no known exploitation of DRUPAL-CONTRIB-2018-008 in the wild and no public exploit code.

Affected product: drupal/entity_ref_tab_formatter. 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.
