## What is DRUPAL-CONTRIB-2018-074?

DRUPAL-CONTRIB-2018-074 is a cross-site scripting vulnerability in drupal/bootstrap, published on 28 Nov 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 base theme bridges the gap between Drupal and the Bootstrap Framework.

The theme doesn't sufficiently filter valid targets under the scenario of opening modals, popovers, and tooltips.

This vulnerability is mitigated by the fact that an attacker must already have the ability to either:

1. Edit/save custom content that supplies a value for the `data-target` attribute by injecting malicious code.
2. Inject custom markup onto the page that further exploits the `data-target` attribute by injecting malicious code. This method of attack is highly unlikely if they already have this level of access.

Note: while the base-theme does not provide either of these opportunities to do this out-of-the-box; a custom sub-theme may, however, be susceptible if it didn't sanitize or filter user provided input for XSS properly.

Check this codebase for DRUPAL-CONTRIB-2018-074 and fix it if it is affected.

What it is: DRUPAL-CONTRIB-2018-074 is a cross-site scripting vulnerability in drupal/bootstrap, published on 28 Nov 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-2018-074 in the wild and no public exploit code.

Affected product: drupal/bootstrap. 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.
