## What is DRUPAL-CONTRIB-2017-082?

DRUPAL-CONTRIB-2017-082 is an authentication bypass vulnerability in drupal/permissions_by_term, published on 8 Nov 2017. Any signed-in user can exploit it over the network, with no action from the victim.

### Official description

The Permissions by Term module extends Drupal by adding functionality for restricting access to single nodes via taxonomy terms.

The module grants access to nodes that are being blocked by other node access modules and that the Permissions by Term module does not intend to control. Additionally, it grants access to unpublished nodes in node listings to users who should not be able to see them. These problems lead to an access bypass vulnerability.

This vulnerability is mitigated by the fact that it only occurs on sites that either have another node access module (besides Permissions by Term) in use, or that have node listings that are accessible to unprivileged users and that don't directly filter out unpublished content.

Check this codebase for DRUPAL-CONTRIB-2017-082 and fix it if it is affected.

What it is: DRUPAL-CONTRIB-2017-082 is an authentication bypass vulnerability in drupal/permissions_by_term, published on 8 Nov 2017. 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-2017-082 in the wild and no public exploit code.

Affected product: drupal/permissions_by_term. 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.
