## What is DRUPAL-CONTRIB-2023-016?

DRUPAL-CONTRIB-2023-016 is a cross-site scripting vulnerability in drupal/iubenda_integration, published on 31 May 2023. An attacker needs administrator access to exploit it, and only if a user opens a file or follows a link.

### Official description

The Iubenda Integration module provides a custom block to provide a link to the Iubenda privacy policy. On this block, a custom prefix and suffix text can be entered.

The module does not sufficiently filter the block text fields on output, resulting in a Cross-Site Scripting (XSS) vulnerability.

This vulnerability is mitigated by the fact that an attacker must have a role with permission to use the layout builder on content, edit the layout, or with the "Administer blocks" permission.

Check this codebase for DRUPAL-CONTRIB-2023-016 and fix it if it is affected.

What it is: DRUPAL-CONTRIB-2023-016 is a cross-site scripting vulnerability in drupal/iubenda_integration, published on 31 May 2023. An attacker needs administrator access to exploit it, and only if a user opens a file or follows a link.
Exploitation: There is no known exploitation of DRUPAL-CONTRIB-2023-016 in the wild and no public exploit code.

Affected product: drupal/iubenda_integration. 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.
