## What is DRUPAL-CONTRIB-2022-019?

DRUPAL-CONTRIB-2022-019 is a vulnerability in drupal/vendor_stream_wrapper, published on 25 Jan 2022. An attacker can exploit it over the internet without logging in, with no action from the victim.

### Official description

This module provides a stream wrapper for files located in the vendor directory. Even when the vendor directory is moved outside the webroot, it allows providing publically accessible URLs to these files.

The module exposes all files that are in the vendor directory, without a site owner's knowledge or intention. This could be undesirable behavior, especially since this module is required as a dependency by other modules.

Check this codebase for DRUPAL-CONTRIB-2022-019 and fix it if it is affected.

What it is: DRUPAL-CONTRIB-2022-019 is a vulnerability in drupal/vendor_stream_wrapper, published on 25 Jan 2022. 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-2022-019 in the wild and no public exploit code.

Affected product: drupal/vendor_stream_wrapper. 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.
