## What is DRUPAL-CONTRIB-2020-020?

DRUPAL-CONTRIB-2020-020 is a missing authorization vulnerability in drupal/commerce, published on 27 May 2020. Any signed-in user can exploit it over the network, with no action from the victim.

### Official description

Drupal Commerce is used to build eCommerce websites and applications. It's possible to configure commerce to permit orders by anonymous users. In this configuration, customers who do not choose to create an account upon checkout completion remain anonymous, and the resulting orders are never assigned an owner.

When anonymous users are granted the "View own orders" permission, they are able to see any such anonymous order via direct navigation to its view page. The module does not include extra access control necessary to ensure anonymous users are only able to view their own previously placed orders.

This vulnerability is mitigated by the fact that a site must be configured to permit anonymous checkout and an attacker must be an anonymous user with the permission "View own orders".

Check this codebase for DRUPAL-CONTRIB-2020-020 and fix it if it is affected.

What it is: DRUPAL-CONTRIB-2020-020 is a missing authorization vulnerability in drupal/commerce, published on 27 May 2020. Any signed-in user can exploit it over the network, with no action from the victim.
Exploitation: There is no known exploitation of DRUPAL-CONTRIB-2020-020 in the wild and no public exploit code.

Affected product: drupal/commerce. 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.
