## What is DRUPAL-CONTRIB-2020-017?

DRUPAL-CONTRIB-2020-017 is a missing authorization vulnerability in drupal/webform, published on 6 May 2020. An attacker can exploit it over the internet without logging in, with no action from the victim.

### Official description

This module enables you to build forms and surveys in Drupal.

The Webform Node sub-module allows these forms to be associated with a Drupal node. The Webform Node module does not implement access checking in the same manner as other nodes and entities. As such, writers of custom modules which implement webform\_node, node, or entity access checks may not achieve the intended access results for Webform Node content.

There is no known exploit of this vulnerability and the vulnerability only exists on sites with custom code and a node access module in use.

What it is: DRUPAL-CONTRIB-2020-017 is a missing authorization vulnerability in drupal/webform, published on 6 May 2020. An attacker can exploit it over the internet without logging in, with no action from the victim.
Exploitation: There is no known exploitation of DRUPAL-CONTRIB-2020-017 in the wild and no public exploit code.

Affected product: drupal/webform. 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.
