## What is DRUPAL-CONTRIB-2021-025?

DRUPAL-CONTRIB-2021-025 is a cross-site scripting vulnerability in drupal/admin_toolbar, published on 25 Aug 2021. Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.

### Official description

The *Admin Toolbar* (`admin_toolbar`) module extends the default toolbar provided by Drupal Core with various features facilitating day-to-day editorial and administrative work.

The *Admin Toolbar Search* sub-module of this module

* doesn't sanitize user input in certain cases, which leads to a Cross-Site-Scripting (XSS) vulnerability. An attacker that can create or edit certain entities, entity bundles or entity types may be able to exploit one or more Cross-Site-Scripting (XSS) vulnerabilities to target users with access to the *Admin Toolbar Search* search box, including site admins with privileged access.
* doesn't properly check access in certain cases, which may result in an information disclosure vulnerability of entity type and bundle labels.

The vulnerability is mitigated by the facts, that:

* the *Admin Toolbar Search* sub-module must be enabled.
* an attacker must have one of several permissions, of which at least some are commonly only assigned to either editors, site builders or administrators.
* a targeted account must have permission to use the search box provided by the *Admin Toolbar Search* sub-module.

What it is: DRUPAL-CONTRIB-2021-025 is a cross-site scripting vulnerability in drupal/admin_toolbar, published on 25 Aug 2021. 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-2021-025 in the wild and no public exploit code.

Affected product: drupal/admin_toolbar. 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.
