## What is DRUPAL-CONTRIB-2021-013?

DRUPAL-CONTRIB-2021-013 is a vulnerability in drupal/graphql, published on 2 Jun 2021. An attacker can exploit it over the internet without logging in, with no action from the victim.

### Official description

This module lets you craft and expose a GraphQL web service API.

The module does not sufficiently protect arbitrary exception and error messages thereby exposing an information disclosure vulnerability.

This vulnerability is mitigated by the fact that a GraphQL server must be enabled and a data producer be configured that throws exceptions with confidential error messages that must not be exposed over the GraphQL API.

Check this codebase for DRUPAL-CONTRIB-2021-013 and fix it if it is affected.

What it is: DRUPAL-CONTRIB-2021-013 is a vulnerability in drupal/graphql, published on 2 Jun 2021. 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-2021-013 in the wild and no public exploit code.

Affected product: drupal/graphql. 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.
