## What is DRUPAL-CONTRIB-2020-002?

DRUPAL-CONTRIB-2020-002 is a cross-site scripting vulnerability in drupal/spamspan, published on 22 Jan 2020. 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 SpamSpan module obfuscates email addresses to help prevent spambots from collecting them.

This module contains a spamspan twig filter which doesn't sanitize the passed HTML string.

This vulnerability is mitigated by the fact that sites must have custom twig template files that use the SpamSpan filter on a field that an attacker could populate. By default the SpamSpan module does not use the vulnerable twig filter.

What it is: DRUPAL-CONTRIB-2020-002 is a cross-site scripting vulnerability in drupal/spamspan, published on 22 Jan 2020. 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-2020-002 in the wild and no public exploit code.

Affected product: drupal/spamspan. 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.
