## What is DRUPAL-CONTRIB-2021-005?

DRUPAL-CONTRIB-2021-005 is a vulnerability in drupal/fac, published on 17 Mar 2021. Any signed-in user can exploit it over the network, with no action from the victim.

### Official description

The [Fast Autocomplete module](https://www.drupal.org/project/fac) provides fast IMDB-like suggestions below a text input field. Suggestions are stored as JSON files in the public files folder so that they can be provided to the browser relatively fast without the need for Drupal to be bootstrapped.

The module doesn't correctly generate certain hashes when the configuration option "Perform search as anonymous user only" is switched from the default on value to off.

This enables a malicious user to read search results generated by users with other roles, disclosing search results the user normally has no access to.

Check this codebase for DRUPAL-CONTRIB-2021-005 and fix it if it is affected.

What it is: DRUPAL-CONTRIB-2021-005 is a vulnerability in drupal/fac, published on 17 Mar 2021. 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-2021-005 in the wild and no public exploit code.

Affected product: drupal/fac. 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.
